B. Summary of the Invention The present invention provides a recording and reproducing apparatus that records a display format for displaying management data of a program recorded on a recording medium in the recording medium, so that the user can customize the display format for each recording medium. Program information can be displayed in a desired display format.

C. Prior Art Conventional consumer video tape recorders record multiple programs on a video tape that extends in the horizontal direction.
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.

D Problems to be Solved by the Invention Incidentally, in this type of video tape recorder, as a method of confirming the contents of a program recorded or reserved for recording on a video tape, recording is performed as management data in a predetermined area at the beginning of the video tape. Alternatively, by recording the contents of the program reserved for recording, and checking it by reading it out and displaying it on a display screen as necessary, the user can simply play the beginning of the videotape. It is thought that the content of the program can be confirmed.

However, the method of displaying the management data is to display the program contents using a display method preset on the video tape recorder itself. For example, the title of the program is displayed in predetermined characters on a predetermined background color. Displayed uniformly depending on the pattern.

Therefore, the user must check the program content by reading the uniformly displayed management data for the program content, making it difficult to visualize the program content and unable to immediately grasp the program content. Additionally, there is a problem in that the user's preferences cannot be reflected on the display screen, and the method is still insufficient as a program management method.

The present invention has been made in consideration of the above points, and is intended to propose a recording and reproducing apparatus that can set various display methods for management data according to the user's preferences.

Evil! Means for Solving the Problem In order to solve this problem, the present invention provides a management database recording area FavvsF^V provided in the recording tracks TA and TB on the distance recording medium 36.

Similarly, in step 5P24, the CPU 8 can designate the recording/operation mode recorded in item B8 of the program information DP, . . . (FIG. 6) and write the recording mode data therein.

Further, the CPU 8 is configured to be able to rewrite the tape type data among the data representing the type of video cassette recorded in the item AIO of the volume information Dv, lx (FIG. 5) in step 5P25.

Further, the CPU 8 in step 5P26 stores the program information Dp.
□ The category code data recorded in item B6 (Figure 6) can be rewritten.

Further, the CPU 8 is configured to be able to rewrite the title data recorded in the item B12 of the program information in step 5P27 (FIG. 6).

In this way, the CPU 8 rewrites the data in the "password" to "title" items in steps 5P23 to 5P27, and then ends the processing of the management database when the "end" item is specified in step 5P28. Then, the process returns to the management database processing loop shown in FIG. 7 and enters the process of step SP8.

On the other hand, when the user clicks on the "cancel reservation" item in the command standby state where the management data list is displayed in step SP21 of FIG. 8, the CPU is recorded in the management data list in step 5P30. Cancel all program reservations.

Also, if the user clicks on the first auto-play mound, C.
PU8 receives the volume information D□ in step SP31.
