Description

Recording medium, recording method, recording device, playback device, data transmission method and server device {RECORDING MEDIUM, RECORDING METHOD, RECORDING DEVICE, REPRODUCTION DEVICE, DATA TRANSMISSION METHOD, AND SERVER DEVICE}

The present invention relates to a recording medium, a recording method, a recording device, a reproduction device, a data transmission method and a server device.

Recording of identification information unique to the recording medium is considered to be a recording medium capable of recording or recording such as a compact disc (CD) or a digital versatile disc (DVD). By recording this identification information, it can be used as an identifier for discriminating whether the recording medium is a true recording medium or an illegally copied recording medium. This identification information can also be used as an identifier for enjoying various services.

Various services are, for example, information (content) that is not particularly related to information recorded on a recording medium or information to be recorded, and related information such as music information, artists related to music information, video information (still images, moving pictures), etc. In some cases, digital data such as program data to be used by a computer is considered. Of course, information related to the information recorded on the recording medium or to be recorded can also be provided as the service content.

By the way, when this identification information is evaluated as one function of an identifier that enjoys various services, for example, a specific service organization is accessed using a terminal apparatus capable of reproducing this recording medium, and the identification information is used for authentication. By using this, it is possible to construct an information service system for enjoying a specific service.

However, there is usually only one service that can be enjoyed in this case. In other words, the identification information and the service that can be enjoyed are in a one-to-one relationship and often have a structure in which only one specific service can be enjoyed by the identification information authenticated by one access. The service is infinite as long as the identification information can be authenticated regardless of whether it is paid or free, and the number of accesses is not limited or the number of service enjoyment is limited.

Therefore, for example, the same service can be repeatedly received, but identification information recorded on the recording medium cannot be used as identification information when, for example, a finite service is provided to the purchaser of the recording medium. However, for example, it is preferable that the number of services that can be enjoyed in accordance with the purchase price of the recording medium can be limited to only this identification information. Or, it is more desirable to be able to limit the number of different content that can enjoy the service. This is because a finite service can be realized by monitoring the number of times of use of identification information and the like on the service organization.

Next, an embodiment of a recording medium or the like according to the present invention will be described in detail with reference to the drawings.

1 shows an embodiment of a disc shaped recording medium 10 which is a writable recording medium according to the present invention. The recording medium 10 has a data recording area 14 and auxiliary recording areas 16 and 18, and the data recording area 14 is an area that can be written from a terminal device (not shown). The auxiliary recording areas 16 and 18 are areas which cannot be written from the terminal device side.

Identification information or the like is recorded in the region 18 which belongs to the innermost periphery of the auxiliary recording areas 16 and 18, and original data (specific content) is recorded in the data recording area 14.

Examples of the recordable recording medium include a recordable CD-R (CD-Recordable) disc, a rewritable CD-RW (CD-Rewritable) disc, and the same recordable DVD-R (DVD-Recordab1e). A disc, a rewritable DVD-RW (DVD-Rewritab1e), etc. are mentioned.

In the optical disc 10, the outermost lead-out area 12 is located, and a program area (PA) 14 which is a content recording area exists therein. This program area 14 corresponds to a data recording area. On the inner circumferential side of the program area 14 is a lead-in area 16 for recording TOC information, and a program memory area (PMA) 18 is formed on the inner circumference thereof. The write lead-in area 16 and the program memory area 18 correspond to the auxiliary recording area.

As is well known, the fake memory TOC information before the complete process or the finalize process is recorded in the program memory area 18. While false TOC information is recorded in the program memory area 18, content data can be written in the program area 14. However, when an operation to be completed is performed, TOC information is written into the lead-in area 16, and subsequent data writing (writing) of content data or the like into the program area 14 cannot be performed.

Fig. 2 shows an optical disc 10a as a recording completed recording medium in which data is recorded by the pressing process. The optical disc 10a is composed of a program area 14a which is a data recording area in which data is recorded, a lead-out area 12a and an inner circumferential side lead-in area 16a on its outer circumferential side. As the recorded recording medium, a typical optical disk is a CD-ROM disk, a DVD ROM disk, or the like.

A plurality of identification information UIDs are recorded for the recording media 10 and 10a shown in these FIG. 1 or FIG. The identification information UID is for acquiring the information (service content, etc.) accumulated in the management server when the specific management server is accessed. It is used as a kind of service for a person who regularly purchases the recording mediums 10 and 10a.

A plurality of identification information UIDs are recorded on the recording mediums 10 and 10a. As the identification information UIDs, only a predetermined number of digits or a combination of these numbers and symbols are constituted. As this identification information UID, in addition to such a data string, the information string which added various accessory information, such as a service method, a service timing (date and time), and a kind of medium, can also be used as identification information. The example described below shows the case where identification information without appended information is used.

As shown in FIG. 3 (A), the identification information UID uses a plurality of items having the same content and a plurality of different identification information UID1 to UIDn (n is any number) as shown in FIG. Is considered.

In the case of the identification information shown in Fig. 3A, for example, it is very suitable for acquiring a specific service content a plurality of times. In the case of the identification information shown in Fig. 3B, for example, when a particular service content is acquired, for example, n service contents having different types are acquired.

The identification information UID is recorded continuously or distributed in the above-mentioned area which can be read among the above-mentioned recording mediums 10 and 10a, but cannot be written in the area again. Detailed examples thereof will be described later. In the case of the writable optical disc 10 shown in FIG. 1, address information is recorded as information indicating the position where the identification information UID is recorded in a part of the TOC information while being recorded continuously or distributed in the program memory area 18.

In the case of the recorded optical disc 10a in which data is recorded by the press process shown in FIG. 2, either the lead-out area 12a or the lead-in area 16a starting from the program area 14a or 2 It is recorded continuously or distributed over the above area. Also in this case, information indicating the location of the identification information UID in which area and in which area, i.e., address information, is recorded as part of the TOC information at the same time as the identification information is recorded.

By the way, as shown in Fig. 4, the information service system according to the present invention should be serviced by the terminal device 20 and the server for identifying information management (server device) 30 that has accumulated the service contents. Connected via the circuit network 40 is established.

When the identification information UID read by the terminal device 20 side is transmitted to the management server 30 side, and the identification information UID transmitted by the management server 30 is correctly authenticated, the management server 30 is sent to the management server 30. The accumulated service is provided to the terminal device 20. This service is a bonus for regular purchasers of the optical discs 10 and 10a. For example, a bonus according to the price of the optical discs 10 and 10a, i.e., the service is set in advance, and the user accesses the service. Bonuses, that is, services can be provided to users free of charge.

In FIG. 4, for the sake of simplicity, only one terminal device 20 is connected to the server 30 via the communication line network 40, but in reality, a plurality of terminal devices 20 are connected to the communication line network 40. It is connected to the server 30.

The terminal device 20 has a disc reproducing function and a data transmitting / receiving function, and can read and reproduce original data from the optical discs 10 and 10a, and recorded on the optical discs 10 and 10a. A device for reading identification information UID and receiving a specific service using the read identification information UID. Therefore, the optical discs 10 and 10a described below exemplify a recording completion recording medium such as a CD-ROM disc.

5 shows an embodiment of this terminal device 20, and has a reproducing apparatus 50 for reproducing the optical discs 10 and 10a as described above. This terminal device 20 includes a storage unit for recording and storing various data, starting with the control unit 22 including a CPU that controls the entire device, and in this example, a storage unit 23 composed of a hard disk; A data transmission / reception unit (communication interface) 24 that performs data transmission / reception with the outside is connected to the bus 27. In addition, a display unit 25 such as an LCD or an input unit 26 which is a keyboard or the like for inputting operation information is connected to each other via a bus.

With this configuration, data reproduction including the identification information is started from the optical discs 10 and 10a, and data transmission / reception with the outside via the communication line network and storage processing of the received data are realized. The control unit 22 has a built-in memory (not shown) such as a ROM that stores processing programs necessary for realizing these processes.

6 shows an embodiment of the management server 30. The management server 30 is configured to authenticate the identification information transmitted from the user, to provide a service prepared in advance when the transmitted identification information is correctly authenticated, and to perform the process of managing the service count and the like.

Therefore, as shown in Fig. 6, the management server 30 includes a control unit 31 composed of a CPU that controls the entire server, a database (memory unit) 32 storing service content data, and an identification unique to the optical disc. A management database 33 that stores various management information such as information UID and service collection is provided. In addition to these, a transmission / reception unit (communication interface) 34 which performs data transmission / reception with the outside via a communication line network, a display unit 35 which is an LCD for displaying information such as identification information UID, etc., and a keyboard used for information input, An input unit 36 or the like such as a mouse is connected by the bus 37.

7 is a system diagram of an essential part showing an embodiment of a reproducing apparatus 50 according to the present invention.

The servo controller 52 is controlled by the control signal from the control unit 22. The spindle motor 54 is rotated so that the optical disk, for example, the optical disk 10a is in a rotational state where the linear velocity is constant. The recording information from 10a is read by the optical pickup (head portion) 55. The reflected light from the optical disk 10a is photoelectrically converted into a photo disk of the optical pickup 55 and converted into an electrical signal, and the output signal from the optical pickup 55 is demodulated (demodulation processing unit) 57 through the RF amplifier 56. ), And demodulation (EFM demodulation) processing is performed.

The output signal corresponding to the data read out from the program area 14 among the output signals from the demodulator 57 is further subjected to error correction processing and decoding processing by the error correction and decoding circuit 58 at a later stage. Thereafter, the output signal from the output processing unit 59 is also supplied to the extraction unit 62 of the identification information again while being output as a reproduction output signal through the output processing unit 59, and the gender information recorded on the optical disc 10a. UID is extracted and separated.

On the other hand, the demodulation output signal EFM demodulated by the demodulator 57 is also supplied to the TOC reading section 60 which extracts the TOC information, and extraction and separation of the TOC information is performed. The extracted TOC information is supplied to the control unit 22, and the address information on which the identification information UID is recorded is extracted from the TOC information. Using this address information, only the identification information UID is extracted and separated from the output signal from the output processing unit 59 supplied to the extraction unit 62, and this is temporarily written into the memory (RAM) 63 and stored.

The identification information UID of the memory 63 is read in accordance with the input information from the input unit 26, and the read identification information UID is transmitted to the management server 30 side through a transmission / reception unit (not shown).

The original data (video data, etc.) recorded on the optical disc 10a is supplied from the output processing unit 59 to the display unit 25 via the bus 27, so that an image or the like is reproduced and a reproduction device as necessary. It is output to the outside of 50.

By the way, various processing examples at the time of constructing the information service system as shown in FIG. 4 will be described with reference to FIG. 8 and below. Fig. 8 is a schematic diagram (flow chart) for explaining an example of a data transfer method that is an entire process of an information service system. On the terminal device 20 side, an optical disc, for example, an optical disc 10a, is reproduced to identify identification UIDs on an optical disc 10a. Read from and acquire from The identification information UID read out from the optical disc 10a is stored in the memory 63. The identification information UID read out from the optical disc 10a may be displayed on the display unit 25 at the same time, but may not be displayed on the display unit 25 in consideration of safety.

Next, the user performs an access process to the management server 30. At this time, in relation to performing user authentication, the user side transmits the password PW determined in advance with the management server 30 from the terminal device 20 to the management server 30. If the user's authentication is correctly performed based on the password PW transmitted by the management server 30, the menu information (service menu) handled by the management server 30 side is from the management server 30 side. The service menu is transmitted to the terminal device 20, and the service menu is displayed on the display unit 25. When the user selects the service menu using the identification information UID from the displayed service menu, all of the identification information UIDs read from the optical disc 10a are transmitted from the terminal device 20 to the management server 30 side.

The management server 30 performs authentication processing using management information for each recording medium accumulated in the management database 33 as to whether the received identification information UID is normal identification information. This is to prevent illegal access or the like from an optical disc as a illegally copied recording medium. In this case, media-specific management information (information such as identification information) provided from the disc manufacturer or disc vendor is used as the medium management information.

When there is no management information unique to the medium on the management server 30 side, by checking whether the data structure of the identification information UID is a regular data structure or the like, it is true identification information or identification information obtained in an illegal manner, or It is possible to discriminate whether or not identification information created by imitation is negative. When the identification information is true, the identification information UID is registered with the management server 30 side together with the password PW which has been transmitted first.

Subsequently, when the transmission request signal or command of the service information enjoyed by the identification information UID is transmitted from the terminal device 20, the management server 30 selects the service content data. In this case, the service content data corresponding to the received identification information UID is selected to provide the selected service content data to the user side, that is, the terminal device 20.

When the user side transmits specific identification information UIDi to the management server 30, the service server 30 selects the service content data corresponding to the transmitted identification information UIDi, and the service content data is stored in the terminal device 20. Is sent). The user side, that is, the terminal device 20 receives the service content data transmitted. The received service content data is temporarily stored in the storage unit 23 and then reproduced in the display unit 25. Thereby, the service using the identification information UID or identification information UIDi can be provided to the regular purchaser of the optical disc 10a.

When the service content data is serviced, i.e., in response to a request from the terminal device 20, the management information rewriting process of the management database 33 of the management server 30 is performed. For example, when the same service content data is serviced n times, a process of reducing the number of services is performed, and the result is stored in the database 33 as management information. Alternatively, when n different pieces of service content data are serviced, which service content data is provided is stored in the database 33, and the number of times is also stored in the database 33 as management information at the same time.

When the provision of all services corresponding to the identification information UID transmitted from the terminal device 20 is completed, the service relating to the optical disc 10a is terminated. And when all the services are complete | finished, for example, bonus service may be provided. Details will be described later.

In the case of providing a service, the system does not select the service content, but the user side omits the selection of the service and provides only the service content data determined by the server 30 for management in advance with respect to the identification information UID. It can also be built.

Next, the processing sequence will be described in more detail with reference to FIG. 9 and below. For convenience of explanation, a process example of providing only the same service content will be described with reference to FIGS. 9 and 10. First, the management server 30 will be described with reference to FIG. 9.

The management server 30 side first receives all identification information UIDs read out from the optical disc 10a by the terminal device 20 and stores them. The stored identification information UID and management information of the management server 30 are inquired to check whether or not there is a right to receive a service (step 71). That is, it is determined whether there is available identification information UID. Since the service is finite and this depends on the number of identification information, it is determined with reference to the management information whether the access to the management server 30 side is the first time or the second time or later.

As a result of identifying the identification information UID transmitted from the terminal device 20, and when it is determined that the service has not been used up yet, the service content data prepared in advance in response to the transmitted identification information UID is transmitted to the terminal device 20. (Step 72). Prior to the transmission of the service content, in this example, a message for transmitting service content data is first transmitted to the terminal device 20, and then the service content data is transmitted to the terminal device 20. FIG. In the step where the transmission of the service content data is finished, a message indicating that the transmission is completed is transmitted again to the terminal device 20. This is to clarify the start and end of the service content data.

After the service content data is transmitted to the terminal device 20, management information of the management database 33 is rewritten (step 73). For example, when the received total identification information UIDs were five, the number of serviceable times related to the identification information UID peculiar to the medium accessed was decremented and stored by "1", respectively. When the number of possible services remains "1" in the management information, it is determined that the service to the terminal device 20 can be provided.

For example, as shown in Fig. 3A, when five identical identification information UIDs are recorded on the optical disc 10a, the service content data can be received five times. In accordance with the above, when the number of serviceable times is accessed according to the identification information UID from " 5 "

Therefore, as a result of referring to the management information, when neither service is available for any service, it is determined whether the special service (special content data) has already been provided to the user (step 74). The special service is a special service after the completion of all the services accompanying the identification information UID, which is a service provided to the user only once regardless of the number of serviceable times.

When the provision of the special service to the user has not yet been made, the content data prepared as the special service is transmitted to the terminal device 20 (step 75). Also in this case, as described above, a predetermined message is transmitted to the terminal device 20 before and after the content data transmission, and information (identifier) indicating the state where the special service has been provided is identified in the management information of the database 33. It is recorded corresponding to the information UID.

When the transmission of the special service has already finished with respect to the identification information UID transmitted from the terminal device 20, the fact that all the services are finished is notified. That is, in the case of the optical disc 10a in which five pieces of identification information have been recorded, transmission of the service content data to the terminal device 20 is terminated by access to the fifth management server 30, and the sixth management server ( In the access to 30), since the content data for the special service is transmitted to the terminal device 20, in the case of the access to the seventh management server 30, the provision of this special service has already been terminated. A message indicating that the service is terminated is sent to the user, that is, to the terminal device 20, so that all the services relating to the optical disc 10a are terminated (step 76).

10 shows an example of processing on the user side. After all identification information UIDs have been transmitted to the management server 30, the terminal device 20 enters the standby mode, and the data transmitted from the management server 30 side is serviced. It is determined whether the message data is sent at the time of content data transmission (step 81), and when the message data is sent at the time of service content data transmission, a transmission start message is displayed on the display section 25 in accordance with the received data (step 82). ). The service content data is transmitted from the server 30 following this transmission start message, and is received, stored in the storage unit 23, and stored (step 83). In some cases, the content of the service content data may be displayed on the display unit 25 at the same time. When the reception of the service content data ends, data relating to the transmission end message is transmitted from the management server 30 afterwards, so that the transmission end message is displayed on the display unit 25 (step 84). Thereafter, the terminal apparatus 20 enters a reception waiting state until the next service content data is transmitted (step 85).

On the other hand, when it is determined that the data received in step 81 is not the message data sent at the time of transmission of the service content data, the data transmitted from the management server 30 next is sent at the time of sending the special service data. It is determined whether or not the data is related to the message (step 87). When it is determined that the message is sent at the time of transmission of the special service data, the content data for the special service is received, and the received data is stored in the storage unit 23 or displayed on the display unit 25 (step 88). Thereafter, data relating to the message for which all services transmitted from the management server 30 are terminated is received, and a message of service termination is displayed on the display unit 25 in accordance with the received data (step 89).

In step 87, when it is determined that the received data is not the message data sent at the time of transmission of the special service, the data transmitted from the management server 30 is a message indicating that all the services have ended. The display unit 25 displays a message indicating that all services have ended.

In this way, the user can enjoy the content data for the service prepared on the management server 30 side only by transmitting the identification information UID read out from the optical disc 10a to the management server 30 side. The content data that can receive the service is the same content data or different content data for each access to the management server 30. In this example, however, the user cannot specify the content data of the preference.

As described above, when the number of services is managed on the management server 30 side, the number of services is managed with reference to the identification information UID read from the optical disc 10a, so that the terminal apparatus 20 does not depend at all. . Therefore, even if the identification information UID is read out using the different terminal apparatuses 20, the service management for the optical disc 10a is complete, and no service beyond the service limit is provided to the user.

Next, another Example is described with reference to FIGS. 11-14. This embodiment is a case where the user can select content data for a service that can receive a service. In this case, as shown in Fig. 11, a target list of individual identification information UIDs of all the identification information UIDs transmitted by the user and the content data for the service is created and stored in the management database 33. Leave it. It is arbitrary which content data for service is assigned to which identification information UID, but it extracts with reference to a predetermined content data table. As shown in Fig. 12, in the list, an identifier indicating that the service has been received in the service termination column is written in the list when the user has already received the service with respect to the identification information UIDi transmitted by the user for receiving the service. . In FIG. 12 for convenience, a mark indicates that the user has already received the service.

In the first access, the service termination column is blank as shown in FIG. 11. Which content data service in this list is transmitted to the nostalgia or the user is arbitrary. When the user enjoys the service of the content data corresponding to the transmitted identification information UIDi or the user is sent to the terminal device 20, Fig. 12 The service end identifier is added or added as shown. Since the list shown in FIG. 12 is presented to the user at the time of accessing the management server 30 after the second time, the user selects from the content data for the remaining services.

Processing examples related to FIGS. 11 and 12 are shown in FIGS. 13 and 14.

13 shows an example of processing on the management server 30 side, when all identification information UIDs are received from the terminal device 20, it is first determined whether the received identification information UIDs are valid, and when it is determined that they are valid, that is, When there is an available identification information UID that can be provided with the service (step 91), a target list of all the identification information UIDs received in advance and the serviceable content data is created and is displayed on the user side, that is, the terminal device 20. It transmits (step 92).

Since the specific identification information UID is specified by the user according to the transmitted list, the content data for the service corresponding to the identification information UID selected or designated and transmitted by the user is transmitted and provided to the user (step 93). At this time, as described with reference to Fig. 10, message data relating to the transmission start and the transmission end are respectively transmitted before and after the transmission of the content data for service (step 94). Thereafter, in the management information stored in the management database 33, which identification information UIDi is designated by the user by this access (step 95). At the same time, as shown in Fig. 12, information in the schedule is updated, i.e., an identifier indicating service termination is entered.

As shown in Fig. 12, by updating the list, the next time access according to the identification information UIDi is from the user side, it is determined whether the service can be provided to the user again, and when there is an identification information UIDi that can be used. (Step 96), when the user is inquired about whether or not to receive the service (step 97), and when the user receives data or a command indicating that the user is to receive the service continuously (step 98), the process returns to step 92 again. Is sent to the user, and the content selection process is performed as described above.

When all the initial services are used up in step 96, that is, when all the identifiers are written in the service termination column of the table shown in Fig. 12, the processing for the special service prepared in advance is performed (step 101). When the user has not yet enjoyed the special service, in order to provide the user with content data for the special service, the content data for the special service is transmitted to the user, that is, the terminal device 20 together with the data about the transmission start message. In the step where the transmission is completed, the transmission end message is transmitted to the terminal device 20 to end the service processing (step 102).

On the other hand, when the user is already receiving the special service, no further service can be received with respect to the optical disc 10a. In this case, the end message of all the services is the user, i.e., the terminal device. It transmits to 20 and ends the process of FIG. 13 (step 103). When the user accesses the management server 30 several times, the number of services for the identification information UID transmitted from the user may be exceeded. In this case, by referring to the list shown in Fig. 11 which is the content of the management database 33, it is possible to determine that no usable identification information UID exists (step 91). In that case, the determination of step 101 is awaited.

In the access for the service number corresponding to the identification information UID, since the user has not yet enjoyed the special service, the process proceeds to step 102 in this case, and when the access exceeds the service number, the process proceeds to step 103.

14 shows an example of processing on the user side. After all identification information UIDs are transmitted to the server 30, the terminal device 20 enters the standby mode, and the data transmitted from the management server 30 side is the final service. It is determined whether or not the message is related to the end (step 111). If it is determined in step 111 that the data indicates the identification information UID and the schedule related to the service content, the table is displayed on the display unit 25. (Step 112). The service content data to be provided from the displayed list is designated by the identification information UID (step 113).

Next, the transmission start message is displayed on the display unit 25 in accordance with the data transmitted from the management server 30 (step 114). Since the service content data is transmitted from the management server 30 following this transmission start message, the service content data is received, written in the storage unit 23, and stored (step 115). In some cases, the content of the service content data may be displayed on the display unit 25 at the same time. When the reception of the service content data ends, the transmission end message is then displayed on the display unit 25 in accordance with the data transmitted from the management server 30 (step 116). After that, the terminal apparatus 20 enters a reception waiting state until transmission of the next service content data (step 117).

When the user wishes to continue the next service in step 117, the user operates the input unit 26 to request the management server 30 to resend the list (step 118). On the management server 30 side, the list stored in the management database 33 is updated in accordance with the latest reception information from the terminal device 20, so that the request from the user, i.e., the terminal device 20, is received. The latest schedule will be resent. Thereafter, it is determined whether the received data is data indicating a service end message (step 119), and when it is determined in step 119 that it is data relating to a service end message, then the data indicates the start of transmission of the special service. It is determined whether or not the data is about (step 120). When the data relating to the message indicating the start of the special service is transmitted in step 120, the content data for the special service subsequently transmitted from the management server 30 is received and stored in the storage unit 23 or the display unit 25. (Step 121). After that, when data indicating that all the services have ended is received, a message is displayed on the display unit 25 in accordance with the received data (step 122).

In step 120, when it is determined that the received data is not data indicating the start of the transmission of the message for the special service, the received data is data indicating that the service has ended, as in the case of step 119, and therefore the process proceeds to step 122. The message of service termination is displayed on the display unit 25.

As described above, it is possible to receive a finite collection of services while selecting service content data according to the taste of the user. In this case, adopting identification information of different contents shown in Fig. 3B as the identification information UID to be used tends to take a correspondence with the service contents.

By the way, as shown in FIG. 2, even in the press-processed data recording completed recording medium, a plurality of identification information can be recorded and used on this medium. In this case, the identification information UID is additionally recorded using, for example, a high power laser, on the optical disc as a recording medium on which desired data is written. An example of the recording method is described below with reference to FIG. 15.

15 shows an example of an optical disc creation system including an identification information recording apparatus. This optical disc creation system includes a modulation signal transmitting device 140 for generating and transmitting a modulation signal of data recorded on an optical disc, and a laser beam recorder 600 which is an optical disc master recording device for creating an optical disc master 320 in accordance with the modulation signal. , A forming apparatus 700 for forming a disk substrate using a stamper 330 created on the basis of a disk made by the recorder 600, and a recording apparatus 200 for performing additional recording on the optical disk 340 of the semi-finished product. do. The additional device 200 is a device for recording the above-mentioned identification information UID.

The modulation signal transmitting device 140 includes modulation information for converting the data reproduced by the recording information reproducing unit 150 and the recording information reproducing unit 150 to read and reproduce data recorded on the optical disc. The generation unit 160 includes a modulation information storage unit 170 for storing a modulation signal supplied from the generation unit 160, and a modulation signal output unit 180 for outputting the modulation signal.

The recording information reproducing unit 150 sequentially reads and reproduces the predetermined data recorded on the optical disc 310 serving as the master in accordance with the entire area, and sends it to the modulation information generating unit 160. As the master optical disc 310, it is a master medium (information source) such as a CD-R disc, and predetermined data recorded on the optical disc master 320 is recorded. The predetermined data is arbitrary data such as music data, video data, or a program.

The modulation information generation unit 160 converts the data reproduced from the optical disc 310 serving as the master into a modulation signal of a predetermined predetermined format, and stores the generated modulation signal in the modulation information storage unit 170 and simultaneously modulates the modulation signal. Output to the output unit 180. The modulated signal is constituted by a bit pattern composed of "1" and "0" converted by a predetermined format. At the time of modulation, if necessary, reference is made to the recording related information 410 relating to additional recording such as designation of a region to perform additional recording, and modulation processing is performed so that any specific pattern described later is formed on the optical disk.

The modulation information storage unit 170 stores the modulation signal generated by the modulation information generation unit 160. The modulated signal output unit 180 inputs a modulated signal generated by the modulated information generator 160, and outputs a modulated signal by outputting a bit pattern including “1” and “0” corresponding to the modulated signal to a predetermined clock. It generates and outputs to the laser beam recorder 600.

The laser beam recorder 600 is input from the modulated signal transmitting device 140 and modulates the laser light according to the modulated signal to irradiate the optical disc master 320, thereby cutting the master 320, that is, modulating the master disc 320. Recording is performed by the laser beam. According to the optical disc master 320, a stamper 330 is manufactured.

The molding apparatus 700 uses this stamper 330 to shape the disk substrate on which the uneven pattern corresponding to the data to be recorded is formed. The optical disc 340 of the semifinished product is formed by a reflective film and a protective film formed on the molded disk substrate, and represents an optical disc in a state in which additional information is not yet recorded.

The additional apparatus 200 is configured according to the modulation information storage unit 210 for storing the additional information related to the additional information 410 or the modulated signal, the additional control unit 220 for controlling the additional recording of the identification information, and the additional control unit 220. The recording unit 230 is configured to perform additional recording of identification information on the optical disc 340.

The modulation information storage unit 210 stores the write-related information 410 used by the modulation signal transmission device 140 and the modulation signal output by the modulation signal transmission device 140. The additional control unit 220 calculates an area for recording the additional information 420 according to the additional recording related information 410 or a modulation signal, and controls to additionally record additional information 420, that is, identification information, in the calculated area. Is done.

The recorder 230 records, according to the record controller 220, record additional information 420, which is identification information unique to an optical disk stored in a memory (not shown), on the optical disk 340 of the semifinished product, and the recordable information 420 is An optical disc 350 as a recorded finished product is created. The optical disc 350 points to the recording medium 10a in which the plurality of identification information described above is recorded.

In the recorder 200, the record-related information 410 used in the modulated signal transmitting device 140 or a data pattern corresponding to the modulated signal is stored in the modulation information storage unit 170 in advance. The additional recorder 220 calculates an area for recording the additional information 420 on the optical disk 340 according to the additional data related to the additional record 410 or the modulation signal, and adds the additional information 420 to the calculated area. The additional control unit 230 to record additional. The recorder 230 records the recordable information 420, that is, the identification information, on the optical disc 340 of the semi-finished product in accordance with the recordable control unit 220 to produce an optical disc 350 as a finished product.

As a recording method of identification information as additional information, in the modulation signal transmitting device, a modulation signal having an unmodulated section formed in an arbitrary section of the modulation signal at the time of modulation of the information data is produced to produce an optical disc of semi-finished product. There is a method of recording additional information in an unmodulated section to produce an optical disc as a finished product.

An example is shown in FIG. In the modulation signal transmitting device 140, information about an unmodulated section to be inserted into a data pattern (hereinafter referred to as an EFM data pattern) according to the modulation signal is obtained from the additionally related information 410. For example, it is obtained from the record-related information 410 where to insert the unmodulated section or the number of unmodulated sections of the EFM data pattern.

The manufacturer of the optical disc may arbitrarily select where to insert the unmodulated section and how many unmodulated sections to be inserted. However, the semi-finished optical disc 340 in which the unmodulated section is inserted is set such that tracking of spots irradiated onto the optical disc can be controlled, that is, the continuous unmodulated section is less than or equal to the servo band of the tracking control.

This tracking control method includes various various methods and is not particularly limited. In the example of FIG. 16, the sub-coding unit in which the sub-code data is originally recorded is an unmodulated section. The non-modulated section can be formed at any location in the program area in which data on the optical disk except for the synchronization pattern is recorded, except for this sub coding section. A plurality of unmodulated sections may be formed at regular intervals or at random intervals other than forming the unmodulated sections so as to be below the servo band of the tracking control.

The modulation information generation unit 160 functioning as a modulation processing unit generates a modulation signal (hereinafter referred to as an EFM signal) in which an unmodulated section is formed in a part of the EFM data pattern according to such additional recording related information 410. And outputs to the laser beam recorder 600. As for the waveform of the EFM signal output to the laser beam recorder 600, that is, the EFM signal recorded on the optical disc master 320, the signal level of the portion corresponding to the sub coding part becomes "O". In the semifinished optical disc 340 produced according to this, as shown in Fig. 16, pits do not exist in the sub-coding portion which is an unmodulated section in the state before recording the additional information 420.

Thereafter, the recording unit 230 functioning as a recording unit is irradiated to the sub-coding unit of the optical disc 340 with a high output laser light, for example, so that the reflective film of the optical disc 340 is modified to perform additional recording as identification information. The information 420 is additionally recorded. After additional recording of the additional information 420 is performed, pits are formed in the sub coding section in accordance with the additional information 420 as shown in FIG.

The sub coding section in which the additional information 420 is additionally recorded is read out early when the sub code data originally recorded in the sub coding section of the optical disc 350 is read. As described above, the sub-coding section in which the additional information is recorded is accessed when reading the identification information from the optical disc 350. The plurality of additional information 420 may be recorded in one sub coding unit, or the plurality of additional information may be recorded over the plurality of sub coding units.
