Description

Batch recording method of optical disc device batch method {Method for recoding data in CD recorder}

The present invention relates to a method for collectively performing a write completion operation of an optical disc apparatus which automatically performs a finalize operation on an optical disc after completion of recording of the requested data without a separate key input by a user.

In general, an audio CD recorder (ACDR) adopts a track at once (TAO) recording method as a data recording method for an optical disc. Accordingly, the data recorded on the optical disc has the form shown in FIG.

Since the ACDR records in the TAO recording method unconditionally even when the recording mode is a disk dubbing mode, that is, a disk copy, the user waits until the recording operation is completed before recording. A separate key must be input to finalize the optical disc. If the user does not enter a key to complete the recording, the TOC information, which is the playlist information for the recorded data, is displayed on the optical disc. Since the recording is not recorded in the lead-in area of the CD-Player, the CD-Player which performs the playback operation using the TOC information cannot play back the optical disc that has not been finalized.

Therefore, even in the disc dubbing mode, the user always waits for a long time during which the recording operation is performed, and when the recording operation is completed, the user must input a key to complete the recording.

Accordingly, the present invention has been created to solve the above problems, and according to the size of the data to be recorded, the recording mode, and the like, the recording is completed on the optical disk after the completion of recording of the requested data without the user's separate key input. It is an object of the present invention to provide a method for collectively performing a recording completion operation of an optical disc apparatus, which automatically performs an operation and allows an optical disc to be reproduced freely in a general CD player.

FIG. 4 is a flow chart showing a preferred embodiment of a method for collectively performing a recording completion operation of an optical disk apparatus according to the present invention. Hereinafter, with reference to the configuration of FIG. 3, FIG. This will be described in detail.

In the optical disc player (CD-P) 100 and the optical disc recording device (CD-R) 200, respectively, a microcomputer exists, and a microcomputer in the CD-P is a main microcomputer, The microcomputer will operate as a submicrocom.

In this state, when the user requests a recording (S10), the main micom provides information on the size of recording data before transferring the data of the optical disc inserted in the CD-P to the sub-microcom, so that the sub-microcom records the recording. The data received from the CD-P is recorded on the optical disc by using the size information of the data. The recording operation will be described in detail as follows.

First, in a state in which an optical disc is inserted and seated in each of the CD-P 100 and the CD-R 200, when a user requests a recording, the microcomputer of the CD-P 100 records a corresponding recording request with a recording command. The size information of the data is provided to the microcomputer 80 of the CD-R 200. If the user selects songs 1 to 10 of the recorded songs of the optical disc seated on the CD-P 100, When the recording request is made for the recording, the microcomputer of the CD-P 100 provides the microcomputer 80 of the CD-R 200 with the amount of data, namely, size information, for the first to tenth songs requested. Done.

Accordingly, the microcomputer 80 checks the size of data to be recorded on the inserted optical disc 10 from the received size information, and checks the size of the recordable area of the optical disc 10. It is determined whether or not to collectively perform the complete recording operation for the optical disc 10 (sequentially performing the recording operation and the finalize operation) (S11), that is, the recording data is stored in the recordable area. If the size of the remaining area of the recordable area after recording is not smaller than the normal size of one song (for example, 4 minutes), further recording of the song data is possible, so that the finalize operation is performed collectively. If the size of the remaining area of the recordable area is smaller than the normal size of one song (for example, 4 minutes), further recording of the song data is performed later. Since this is impossible, it is decided to perform the finalize operation collectively.

In this state, the microcomputer 80 receives the song data input from the CD-P 100 and records the data on the program (data) area of the optical disc 10. The recording operation is as follows. same.

First, the microcomputer 80 sets the recording speed of the apparatus, and drives the optical disc 10 through the servo unit 60 and the drive unit 70. The digital recording signal processor 30a generates an error correction code (ECC Block) by adding an encoding and an error correction parity for reliability of recording / reproducing the input coded data, and the channel bit encoder. 40 converts the digital bitstream output from the digital recording signal processing unit 30a into a pulse width modulated signal form for recording on the optical disc 10 and applies it to the optical driver 41. Subsequently, the microcomputer 80 controls the optical driver 41 to output a recording signal by an optical driving current corresponding to an optimal recording optical power value, and the optical driver 41 accordingly generates a signal by optical driving power. Is applied to the optical pickup 20 so that the pulse width modulated signal is recorded in the program (data) area of the optical disc 10 (S12). Such a recording operation is performed using the input data (from 1 to 10). Music) is continued until the recording is completed (S13).

When the recording of the recording request data is completed by such a process, the microcomputer 80 performs the finalize operation according to whether the collective completion of the recording completion operation is determined (S20). If it is decided not to perform the recording completion operation collectively, the microcomputer 80 outputs a guide message indicating whether the user should finalize the recording through a display unit (LCD, not shown). When the user makes a separate key input for the finalize, the microcomputer 80 performs a finalize operation on the optical disc 10 (S21), otherwise the microcomputer 80 ) Does not perform the finalize operation. For the optical disc 10 in the non-finalized state, temporary recording information area (PMA: Program Memory Area) is used. Only the temporary recording information for disc playback exists, but no playlist information (TOC) exists in the lead-in area.

By the way, if it is determined in the process to perform a batch complete operation, the microcomputer 80 performs a finalize operation automatically when the data recording is completed (S30), that is, the microcomputer 80 The playlist information TOC of the recorded data is recorded in the lead-in area of the optical disc 10, and the optical disc is reproduced using the recorded playlist information in a general optical disc reproducing apparatus CD-P. (10) to be played back.

FIG. 5 is a flowchart of another embodiment of a method of performing a batch of write completion operations in an optical disk device according to the present invention. Hereinafter, the batch of write completion operations in FIGS. 5 and 5 according to the present invention will be described with reference to FIG. It explains in detail how to perform.

Unlike the above-described embodiment, the embodiment of FIG. 5 determines whether to collectively perform a finalize operation according to the recording mode, which will be described in detail as follows.

When the user requests recording (S40), the main microcomputer of the CD-P 100 transmits a recording command to the microcomputer 80 of the CD-R 200, and accordingly, the microcomputer 80 receives the received recording command. By checking the recording mode according to this, it is determined whether or not to collectively perform the complete recording operation (S41). That is, when the confirmed recording mode is the normal recording mode, the microcomputer 80 completes the recording (Finalize). ) If the checked recording mode is a batch recording mode for performing a batch finalize operation or a disk dubbing mode, The microcomputer 80 decides to collectively perform the finalize operation.

In the state determined as described above, the microcomputer 80 performs the recording operation according to the requested recording mode as described above (S42), and when the recording of the recording requested data is completed (S43), recording according to the above determination Final operation is automatically performed (S50). If the recording mode is a normal recording mode and it is determined that the recording completion operation is not to be performed in the process, the microcomputer 80 completes the recording operation. As described above, only when the user inputs the key, the operation of completing the recording is performed (S51).

By the way, if it is determined in the process that the complete recording operation is performed in the process, the microcomputer 80 automatically performs a recording completion (finalize) operation when the recording of the requested data is completed (S60) After the playlist information TOC is recorded in the lead-in area of the optical disc 10, all the operations are completed.

FIG. 6 is a flow chart illustrating another embodiment of a method for collectively performing a write completion operation of an optical disk apparatus according to the present invention. Hereinafter, the method for performing the collective write completion operation of FIG. 6 according to the present invention will be described with reference to the configuration of FIG. 3. It will be described in detail.

6 may be referred to as a combination of the embodiments of FIGS. 4 and 5, which are as follows.

When the user requests recording (S70), the main microcomputer of the CD-P 100 provides the microcomputer 80 of the CD-R 200 with size information on the corresponding data requested for recording along with a recording command. Accordingly, the microcomputer 80 checks whether the recording mode according to the received recording command is a batch recording mode or a disk dubbing mode.

When the recording result is the batch recording mode or the disk dubbing mode, the microcomputer 80 checks the size of the recording data from the received size information, and also checks the size of the optical disc 10. By checking the size of the recordable area (S71), it is determined whether or not to collectively perform the finalize operation as described above (S72).

As described above, after the completion of the finalize operation is determined, the same process as that of the method of FIG. 4 is performed (S73 to S90). As shown in the method of FIG. 5, after the completion of the recording operation, only the user's key input is performed to perform a recording operation (S81).
