[0002]

2. Description of the Related Art When a plurality of pieces of program information are reserved by using a video tape recorder or the like, a recording position order of a plurality of programs corresponding to the plurality of pieces of program information on a magnetic tape is designated in advance, and the plurality of programs are stored in the designated order. A recording / reproducing apparatus having the technical idea of recording the data on a magnetic tape is disclosed in JP-A-3-40253 and JP-A-3-63952.

FIG. 8 is a diagram for explaining a case in which a plurality of programs stored in a reservation memory are recorded on a magnetic tape in the order of broadcast time. FIG. 8A shows a plurality of pieces of program information reserved in the reservation memory and these pieces of program information. The broadcast time is shown, and (B) shows a state in which a plurality of reserved programs are recorded in order of broadcast time on a magnetic tape. FIG. 9 is a diagram showing a state in which a plurality of reserved programs are recorded in a desired order on a magnetic tape.

As shown in FIG. 8A, a plurality of pieces of program information A to D are reserved in the reserved memory in the video tape recorder. The plurality of pieces of program information A to D are set by keying in the broadcasting station name, day of the week, recording start time, recording end time, and recording mode (standard recording mode or triple recording mode) from a remote controller or the like. In the normal reservation recording, a plurality of programs A _{1 to} D ₁ are sequentially broadcast from the respective broadcasting stations at the broadcasting times shown in the figure, and as shown in FIG. It is recorded in order. By the way, a plurality of program information A ~
Among D, there are program information C corresponding to the program C ₁ to be stored and program information A, B and D corresponding to programs A ₁ , B ₁ and D ₁ that do not need to be stored. T
When it is desired to keep the program C ₁ on the top, if the programs are recorded in the order of the broadcast time, they are recorded after the programs A ₁ and B ₁ that do not need to be saved, and then the program A ₁ that does not need to be saved.
If B ₁ is erased, the use efficiency of the magnetic tape T and the usability of the recording / reproducing apparatus are deteriorated.

Therefore, as shown in FIG.
No. 0253 and JP-A-3-63952 disclose
A plurality of programs A corresponding to a plurality of reserved program information A to D
_A plurality of programs are recorded in a desired order by previously designating the recording position order of _{1 to} D _{1 on} the magnetic tape T.

That is, in Japanese Patent Laid-Open No. 3-40253,
Although illustration is omitted, during the reserved recording period, an index signal is pre-recorded on the magnetic tape according to the recording start position information in accordance with the desired recording order of the program, and is recorded according to the index signal pre-recorded by the sequence control means. Since the playback device is controlled, the recording order of the programs on the magnetic tape at the time when the reserved recording is completed is as specified as shown in FIG.

[0008]

By the way, as described above, JP-A-3-40253 and JP-A-3-639 are used.
According to the publication No. 52, the recording area of the program to be stored can be set preferentially to the recording start position side (upstream side) on the magnetic tape depending on the intention of the user, but both publications have their own problems as described below. There is a point.

First, in JP-A-3-40253, since index signals are pre-recorded on the magnetic tape in accordance with the recording start position information according to the order in which the programs are to be recorded, a plurality of reserved programs are designated. When recording in order, index signal counting means for counting the index signals and corresponding to the corresponding program is required, and the control of the recording / reproducing apparatus becomes complicated. Further, in order to record the index signal on the magnetic tape, it is necessary to run the magnetic tape over the entire recording areas of a plurality of programs to set the entire recording area. There's a problem.

On the other hand, in Japanese Patent Laid-Open No. 3-63952, a control signal for high-speed recording is pre-recorded on a magnetic tape at least in an area required for reserved recording, so that a plurality of reserved programs are designated in the specified order. At the time of recording, a control signal counting means for counting control signals by high-speed recording and corresponding to a corresponding program is required, and the control of the recording / reproducing apparatus becomes complicated.
Furthermore, in order to prerecord the control signal on the magnetic tape, it is necessary to run the magnetic tape over the entire recording areas of a plurality of programs to set the entire recording area. There is such a problem.

[0011]

In order to solve the above problems, a reservation recording apparatus according to the present invention is arranged such that a plurality of program information reserved in a reservation memory and a plurality of programs corresponding to a plurality of programs are recorded on a magnetic tape in order of broadcast time.

Next, in the reservation recording apparatus 10 having the above structure, only the reservation recording function which is the main part of the present invention will be described with reference to FIGS.

As shown in FIG. 2, the G code remote controller 30
Is used to store a plurality of program information A to D in the reservation memory 21 in the reservation recording device 10. It is assumed that the plurality of pieces of program information A to D are stored with the broadcasting station name, day of the week, recording start time, recording end time, and recording mode (standard recording mode or triple recording mode) set, respectively.
Further, it is assumed that the broadcasting time broadcast from each broadcasting station is set in the order of program information A, program information B, program information C, and program information D, as shown in the figure.
The program information C of the plurality of program information A to D is the first program information corresponding to the program to be stored, and the storage information is added by the save button 33 of the G code remote controller 30. A method of specially providing a storage section for a stored program in the reserved memory 21 without using the save button 33 may be considered. On the other hand, the program information A, B, and D among the plurality of program information A to D is the second program information corresponding to the program that does not need to be stored, and the storage information is not added. Therefore, the reserved memory 21 stores the first program information C corresponding to the program C ₁ to be stored and the programs A ₁ and B that do not need to be stored.
_{The first} program information A, B and D corresponding to the first program information D ₁ and the second program information D ₁ are identified and stored.

Here, as shown in FIG. 3, when recording a plurality of programs A _{1 to} D ₁ on the magnetic tape T based on a plurality of program information A to D reserved in the reservation memory 21, it is desired to save them. The program C ₁ is preferentially recorded on the reserved recording start position side (upstream side) of the magnetic tape T, and the programs A ₁ , B ₁ , and D ₁ that do not need to be saved after the desired program C ₁ are saved in the order of broadcast time. The recording operation will be described in detail.

First, in the reserved recording standby state, a plurality of pieces of program information A to D are reserved in the reserved memory 21 to wait for broadcasting from each station, and the magnetic tape T is pulled out from the tape cassette 1. The magnetic tape T is stopped while being wound around the rotary drum 13, and is set at the reserved recording start position on the magnetic tape T. At this time, the reserved recording start position on the magnetic tape T is set based on the user's intention, and when an image is not recorded on the magnetic tape T, the start end portion (start It is set to (after the end side leader tape) or, if there is a recorded image on the magnetic tape T, it is set to the end of the recorded image. Further, on the downstream side from the reserved recording start position on the magnetic tape T, as shown in FIG.
It is unknown whether the audio signal or the control signal has been recorded, that is, the recorded state or the unrecorded state. The pinch roller 18 is separated from the capstan 16 and stands by at the position indicated by the chain double-dashed line in FIG.

Next, description will be made in accordance with the reservation recording operation flow order shown in FIGS.

(Step 1) The first program A among the plurality of programs A _{1 to} D ₁ corresponding to the plurality of program information A to D
_The reservation recording program is started at an appropriate time before the broadcast of ₁ .

(Step 2) The system control section 23 issues an identification command as to whether or not there is program information C with save information in the reserved memory 21, and the first command corresponding to the program C ₁ to be saved is issued from the reserved memory 21. Of the program information C of No. ₁ and the second program information A, B, D corresponding to the programs A ₁ , B ₁ , D ₁ that do not need to be saved, and the program information with the save information (first
Program information) C is selected. Therefore, reserved memory 2
1, the system control unit 23 serves as a stored program information selection unit for performing the operation of step 2.

(Step 3) If there is no program information C with storage information in step 2, a plurality of programs A ₁ , B ₁ , D ₁ corresponding to the program information A, B, D are recorded on the magnetic tape. It is sufficient to record from the reservation recording start position on T in order of broadcast time and end. Hereinafter, this operation is referred to as normal reservation recording.

(Step 4) On the other hand, when there is the program information C with the storage information in the reservation memory 21 in Step 2, the system control unit 23 determines that the stored program C ₁ corresponding to the program information C with the storage information. Whether or not it is broadcast first is identified from the reservation memory 21. If saved program C
_{When 1} is broadcast _first , the stored program C ₁ is recorded from the reservation recording start position on the magnetic tape T as in the normal reservation recording in step 3.

(Step 5) Next, when the stored program C ₁ is not broadcast _first in step 4, the system control unit 23 determines that the first program A 1 which does not need to be stored.
Before ₁ is broadcasted, the program information C with storage information from the reservation memory 21 is taken in and stored by referring to the recording start time, recording end time, and recording mode (standard recording mode or triple recording mode). The tape usage required to record the program C ₁ is calculated.

(Step 6) Next, the system controller 23
Is known from the diameter of the capstan 16, the amount of tape to be sent during one rotation of the capstan 16 is known, and the number of rotations of the capstan 16 corresponding to the tape usage amount of the stored program C ₁ is calculated. The number of rotations of 16 is converted into the number of FG pulses from the capstan motor 17, and this FG is converted.
Calculate the number of pulses. Therefore, the capstan 16, the capstan motor 17, the reservation memory 21, and the system control unit 23 serve as a storage program tape usage amount calculating means for performing the operations of steps 5 and 6.

(Step 7) Next, the system controller 23
At the stage when the tape usage of the stored program C ₁ is calculated,
The pinch roller 18 is pressed against the capstan 16, and an erasing current is sent to the full erase head 14 via the full width erasing circuit section 24. Then, while erasing from the reserved recording start position on the magnetic tape T by the full erase head 14, the magnetic tape T is sent at the constant tape speed by the tape usage amount of the stored program C ₁ , and the destination of the magnetic tape T is sent. Stop running. At this time, the tape usage amount of the stored program C ₁ may be sent by the number of FG pulses calculated previously. Therefore, the full erase head 14, the capstan 16, the pinch roller 18, the system control unit 23, and the like serve as a recording program recording area setting means for performing the operation of step 7. Then, as shown in FIG. 6 and FIG. 7, the recording area of the saved program C ₁ is set from the reserved recording start position on the magnetic tape T, and the control signal already recorded in the recording area of the saved program C ₁ is set. Is erased, and the control signal recording portion is erased even if it is not recorded. Although the full erase head 14 erases the entire width in the embodiment, the control head 15 may erase only the control signal.

(Step 8) Next, the system controller 23
After setting the recording area of the saved program C ₁ , the reservation memory 21 is called to ask whether the next recording is the saved program C ₁ .

(Step 9) If it is determined in step 8 that the program is not the stored program C ₁ , the program A ₁ having the earliest broadcast time among the programs A ₁ , B ₁ , and D ₁ that need not be stored is selected. Record as shown in FIGS. 6 and 7. At the end of the program A ₁ , the control signal is not recorded between the full erase head 14 and the control head 15 as shown in FIG. There is.

(Step 10) Next, the system control unit 2
When the reserved recording of the program A _{1 that} does not need to be stored is completed, 3 determines whether or not the magnetic tape T reaches the end of the tape with a transparent leader tape or the like. If the magnetic tape T has not reached the end of the tape, the process returns to step 8. In this embodiment, when the program A ₁ that does not need to be saved ends, the program B that does not need to be saved subsequently.
₁ is recorded as shown in FIGS. 6 and 7. Also here, the control signal unrecorded portion M is formed at the end of the program B ₁ .

(Step 11) In Step 10,
When the magnetic tape T reaches the end of the tape, the reservation of the program information B and D corresponding to the remaining programs B ₁ and D ₁ that do not need to be saved is forcibly released and the program C to be saved is forcibly released.
_{Since the process} proceeds to step 12 in order to give priority to the recording of _{No. 1} , the programs B ₁ and D ₁ are not recorded because the tape amount is insufficient.

(Step 12) Next, since the control signal is erased from the recording area of the stored program C ₁ set in Step 7, the system control unit 23 determines whether the control signal from the control head 15 exists. The magnetic tape T is fast-rewound while taking in the state via the control signal recording / reproducing unit 25, passes through the recording area of the stored program C _{1 having} no control signal, and the control signal recorded before the reservation start recording position or the start When the end side leader tape is detected, the recording start position of the stored program C ₁ is reached, in other words, the reserved recording start position is reached, and the device waits there. Then, the stored program C ₁ is recorded from the reservation recording start position as shown in FIGS. 6 and 7 in accordance with the broadcast time. Also here, the control signal unrecorded portion M is formed at the end of the stored program C ₁ . Therefore, the control head 15, the system control unit 23, etc.
It serves as a storage area for the stored program for setting the above operation. When the magnetic tape T is rewound quickly, the magnetic tape T only needs to be in contact with at least the control head 15 and need not be wound around the rotary drum 13.

(Step 13) Next, after the recording of the stored program C ₁ is completed, the system control unit 23 inquires of the reservation memory 21 whether there is a next reserved program, and if there is no next reserved program. To finish.

(Step 14) On the other hand, if there is the next reserved program in step 13, the program is fast forwarded from the position where the stored program C ₁ has ended, while checking the presence / absence of a control signal, for example, the end of program B ₁ . The control signal unrecorded portion M formed at the end is detected to wait for the next program, and the next program D ₁ is recorded according to the broadcast time as shown in FIGS. 6 and 7. Hereinafter, programs that do not need to be stored are recorded in the broadcast time order within the recording capacity range of the magnetic tape T.

If a well-known tape remaining amount detecting function is added to the reserved recording apparatus of the present invention having the above-mentioned structure, the reserved recording tape capacity required for the programs A _{1 to} D ₁ from a plurality of reserved program information A to D. It is possible to confirm whether or not is within the tape remaining amount, and the reservation recording program can be further simplified. Even in this case, the recording of the stored program may be prioritized.

[0042]

According to the reservation recording apparatus according to the present invention described in detail above, the first program information corresponding to the program to be stored and the second program information corresponding to the program that does not need to be stored are identified. The recording area for only the stored program corresponding to the first program information is set to the reserved recording start position side on the magnetic tape with the control signal erased. The program to be stored can be surely stored on the reservation recording start position side on the magnetic tape, and the efficiency of use of the magnetic tape and the usability of the reservation recording apparatus of the present invention can be improved.
Further, as compared with the conventional case where the magnetic tape is run over the entire recording areas of a plurality of reserved programs and the entire recording area is set in advance, only the recording area for the stored program is fast-forwarded and set in advance. The reserved recording preparation time can be shortened, and the recording start position of each program can be reliably and easily detected only by the presence / absence of the control signal on the magnetic tape. There are advantages such as simplification.
