B. Summary of the Invention The present invention enables management data of various programs to be recorded and reproduced in a pulse code modulation data recording area in an information recording/reproducing apparatus, thereby making management of various programs even easier.

C. Prior Art Conventional consumer video tape recorders record multiple programs on a longitudinally extending videotape.
A cue signal is recorded at the beginning of each program. For example, when a user wants to play a desired program from a recorded tape, the user must first set the video tape recorder to search mode and use the video tape to cue. After fast-forwarding the signal to a position where it can be played back, the user first switches to playback mode and checks whether it is the program he or she wants to watch.

Problems to be solved by the invention D However, in this conventional video tape recorder,
Information about multiple programs is recorded for each program only at the videotape position where each program is recorded, so that the user can select the program he or she wants to play from one i! When viewing a program, deciding on a program to play, or searching for a program to play, you have to repeatedly search the video tape recorder until you find the program you want to play. There is the complication of having to perform tasks such as fast-forwarding a tape.

In addition, when managing a large number of recorded video tapes or unrecorded video tapes, or when managing so-called series programs recorded across multiple video tapes, it is important to remember that each video tape is actually recorded separately. The content of the program,
There is a complication in that the user has to perform management work such as writing management information such as the recording time and whether or not it is necessary to save on the video tape cassette or cassette case in advance.

However, in practice, the time and effort required to write this management information and to read and judge the written management information are complicated, and the degree of complexity depends on the number of programs and video tapes to be recorded or reserved. The more the value increases, the more it is cumulatively weighted, so it is desirable to simplify it as much as possible.

The present invention has been made in consideration of the above points, and makes it possible to significantly simplify the management of programs when recording, reserving, etc. (this is referred to as recording or reserving) a program. This is an attempt to propose a video tape recorder.

Means for Solving the EyA Problem In order to solve this problem, the present invention provides video recording tracks TA and T formed on the video tape 18.
Audio recording track TAA formed superimposed on B
and TBB and video recording tracks TA and TB in which one or more programs can be recorded, the audio recording tracks TAA and TBB are superimposed on a frequency modulated audio recording area FA and a pulse code modulated audio recording area FA. It has a data recording area FP,
A management database recording area FAV is formed at a predetermined position of the pulse code modulation data recording area FP, management data DAv corresponding to the program is recorded in the management database recording area FAV, and video tape 1 is recorded based on the management data DAV.
To enable management of each program recorded on 9.

Management data DAV regarding programs recorded and reserved on the video tape 19 is recorded in the management database recording area FAV formed in the pulse code modulation data recording area FP of the F-action audio recording tracks TAA and TBB. , the user can access the management data D as necessary.
By simply playing back the Av, information about the programs recorded and reserved on the videotape 19 can be easily grasped as information specific to each videotape 19, and the management data I)Av can be easily grasped as information specific to each videotape 19. By being able to rewrite programs accordingly, management of programs can be made easier.
