First, when the VTR tape is set in the VTR by the tape set 10, the program recording contents of the VTR tape are stored in the program recording content storage unit 1, and the program recording contents are checked by the arithmetic unit 3 ( 2 step 21).

After that, the calculation unit 3 calculates the program recording content of the program recording content storage unit 1 and the reservation content of the reservation data storage unit 2, and the V set by the tape set 10 is calculated.
It is determined whether the program recording reservation can be recorded on the TR tape (step 22 in FIG. 2). In this case, when the calculation unit 3 determines that recording is not possible, an alarm is displayed on the alarm display unit 5 indicating that the reservation content cannot be recorded (FIG. 2).
Step 23).

On the other hand, when the arithmetic unit 3 determines that recording is possible,
The tape control unit 6 calculates the VTR based on the calculation result of the calculation unit 3.
The tape can be recorded for the recording time of the reserved content and is moved to the area of the closest recording time, that is, the optimum position. At this time, the calculation unit 3 updates the program recording content corresponding to the position with the reservation content (step 24 in FIG. 2).

After that, when the recording start time comes, the VTR
Recording on the tape is started (step 25 in FIG. 2), and when the recording end time comes, recording on the VTR tape ends (step 26 in FIG. 2).

When the recording on the VTR tape is completed, the arithmetic unit 3 determines whether or not there is a next reservation (step 27 in FIG. 2), and if there is a next reservation, the above-mentioned steps 22-2.
The operation 7 is performed, and if there is no next reservation, the reservation recording of the program is ended.

FIG. 3 is a diagram showing the structure of a VTR tape according to an embodiment of the present invention. FIG. 3A shows a case where the program record contents of each program recorded in the program recordable area are collectively stored in the program record content information area at the beginning of the tape of the VTR tape.

Further, FIG. 3B shows a case where, for each program recorded in the program recordable area of the VTR tape, the program record content corresponding to the program record content information area at the beginning thereof is stored. That is, the program record content of the program is stored in the program record content information area at the beginning thereof, and the program record content of the program is stored in the program record content information area at the beginning thereof.

FIG. 4 is a diagram showing an example of the program recording contents stored in the program recording content storage unit 1 of FIG. In the figure, the program record content storage unit 1 stores the date, time, channel, mode, and presence / absence of "protection" read from the program record content information area of the VTR tape.

In FIG. 4, the program of "1ch (channel)" is recorded in "standard" mode at "13:00 to 14:00" of "January 1, 1993" on the first of the VTR tape. It indicates that

The second VTR tape is "3ch on" 11:00 to 11:30 "of" January 2, 1993 ".
(Channel) ”is recorded in the“ standard ”mode.

Furthermore, "93" is added to the third VTR tape.
It indicates that the program of "4ch (channel)" is recorded in "standard" mode at "9:00 to 9:30" of "January 3, 2014".

In order to prevent erasure of the second recorded program of the above-mentioned recorded programs, "protection" is written in the program recorded contents corresponding to the second recorded program. Since the first and third recorded programs may be deleted,
"Protection" is not written.

FIG. 5 is a diagram showing an example of the reservation data stored in the reservation data storage unit 2 of FIG. In the figure, the reservation data storage unit 2 has a reservation date indicating a program date to be recorded on a VTR tape, a reservation time indicating a program time to be recorded, a channel indicating a channel of a program to be recorded, and recording in a "standard" mode. A mode indicating whether the program is to be performed or the “3 × speed” mode and the presence / absence of “protection” indicating whether to save the recorded program are written via the data input unit 4.

In FIG. 5, as the first reservation data, the recording of the program of "1ch (channel)" at "7:00 to 7:25" of "Jan. 4, 1993" in the "standard" mode is reserved. It shows that it is doing.

As the second reservation data, "9
"1ch to" 8:00 to 8:50 "of" January 4, 3rd "
It indicates that the program of "(channel)" is reserved for recording in the "standard" mode.

Further, as the third reservation data,
It indicates that the program of "1ch (channel)" is reserved for recording in the "standard" mode at "10:00 to 10:40" on "Jan. 4, 1993". Incidentally, "protection" is written in order to save all the above-mentioned first to third reservation data.

FIG. 6 is a diagram showing a recording operation when a recording reservation is made in the embodiment of the present invention. In the figure, the VTR tape recorded with the program recording content shown in FIG.
The operation when the reserved program is recorded with the reservation data shown in FIG. The reserved recording operation according to the embodiment of the present invention will be described with reference to FIGS.

The tape control operation of the VTR when the recording contents of the VTR tape set in the VTR are the contents shown in FIG. 4 and the reservation data shown in FIG. 5 are provided will be described below. The VTR tape in this case is 120 in standard mode.
Minute recording is possible.

VT already recorded with the program recording contents shown in FIG.
When recording on the R tape again, the part that can be recorded is VT
The first recorded part of the R tape (60 minutes) (of FIG. 6) and the third recorded part of the VTR tape (3)
0 minutes) (of FIG. 6). Since "protection" is written in the second recorded portion (30 minutes) of the VTR tape (in FIG. 6), recording cannot be performed.

In this state, the tape control unit 6 searches for the optimum portion for recording based on the first reservation data. Since the recording time of the recording based on the first reservation data is "25 minutes", when the tape control unit 6 determines that the recording on the VTR tape portion is optimum, the tape control unit 6 moves the VTR tape to the optimum position A, and The program indicated by the first reservation data is overwritten and recorded on the tape portion.

When the recording of the program indicated by the first reservation data is completed, the remaining amount from the recording end position B to the end of the VTR tape is only 5 minutes, so the recording time is 2/50.
The program shown in the second reservation data cannot be recorded in that part.

Therefore, the tape control unit 6 searches for the optimum portion for recording based on the second reservation data. Since the recording time for recording based on the second reservation data is "50 minutes",
When the tape control unit 6 determines that the recording on the portion of the VTR tape is optimum, the VT is reached to the optimum position, that is, the tape start
The R tape is moved, and the program indicated by the second reservation data is overwritten and recorded on the portion of the VTR tape.

When the recording of the program indicated by the second reservation data is completed, the remaining amount from the recording end position to the VTR tape portion where recording is prohibited is only 10 minutes, so the recording time is 40 minutes. The program shown in the third reservation data cannot be recorded in that part. Therefore, further recording on the VTR tape cannot be performed, and the fact is displayed on the alarm display unit 5 as an alarm.

As described above, the program recorded on the VTR tape is stored by storing at least the program recording content indicating the recording date and time and the presence or absence of protection corresponding to each program recorded on the VTR tape. Since it is possible to determine whether or not each is a recorded portion to be saved, the recorded V
Even when the reserved recording is performed using the TR tape, it is possible to save only the recording portion to be saved.

When the program recording reservation is made, the arithmetic unit 3
On the basis of the contents of the program recording contents storage unit 1 and the contents of the reservation data storage unit 2, it is judged whether or not it is possible to record the program recording reservation on the set VTR tape, and when it is judged that the recording is impossible, an alarm is issued. By displaying an alarm on the display unit 5 and moving the VTR tape to the recording portion of the recording time closest to the recording time indicated by the reservation data by the tape control unit 6 when it is determined that the recording is possible, Even when performing reserved recording using a recorded VTR tape, it is not necessary to manually move the recording portion to be saved, and the VTR tape is automatically recorded to the most appropriate portion of the recordable recording portion. It is possible to move to a desired location for scheduled recording.

Therefore, even when the reserved recording is performed by using the recorded VTR tape, only the recording portion to be preserved can be preserved. In this case, the recorded content of the program is VT
By storing the program at the beginning of each program recorded on the R tape, it is not necessary to calculate the tape length when searching for the most appropriate part of the recordable recording parts.
It is possible to search the most appropriate part at high speed.

Although the VTR tape has been described as the program recording medium in the embodiment of the present invention, it is obvious that the present invention can be applied to other recording media capable of recording and reproducing the program, and the present invention is not limited to this.

[0044]

As described above, according to the program recording medium of the present invention, a recording storage area for storing program recording contents,
By providing at least the recording date and time of the program recording content stored in the recording storage area and the recording content storage area for storing the recorded content indicating the presence or absence of protection, the recorded VT is recorded.
Even if the R tape is used for the reserved recording, there is an effect that only the recording portion to be preserved can be preserved.

Further, according to the recording / reproducing apparatus of the present invention, the program storing the recording reservation content set from the outside and the recording content indicating at least the recording time and the protection of the program recording content stored in the recording storage area. Comparing with the contents of the recorded contents storage area of the recording medium, it is judged whether or not recording based on the recording reservation contents is possible on the program recording medium, and when it is judged that the recording is impossible, an alarm is displayed. Thus, there is an effect that it is possible to save only the recording portion that is desired to be saved even when the reserved recording is performed using the recorded VTR tape.
