By the way, the conventional video tape T on which the table-of-contents screen information is recorded by the video recording / reproducing apparatus as described above has a plurality of recorded software P ₁ ,
Of the contents of P ₂ , ... P _n , only the table-of-contents screen information (video information) is recorded, and the audio information (audio information) accompanying these is not recorded. When I check the contents, I am still lacking in power. Further, in the above-mentioned conventional technique, the table-of-contents screen information is recorded only at the start end of the video tape T. Therefore, the table-of-contents screen information cannot be confirmed unless it is returned to the beginning of the long video tape T. When T is waiting in the middle position or when the reproduction of the desired software is completed and the next desired software is searched, there is a drawback that the table of contents screen information cannot be immediately confirmed.

Further, although not shown, in a video disk drive device using a video disk as a recording medium, a plurality of pieces of software recorded on the video disk are reproduced by an optical pickup. Random access is possible instantly by moving at high speed in the radial direction. However, even in a video disc that can be accessed at high speed, there are some that record guide information corresponding to a plurality of software, song title information corresponding to a plurality of software, and the like as table-of-contents information near the lead-in area of the video disc. However, since the table-of-contents information recorded on the video disc is almost only textual information, the contents of each software cannot be grasped in detail collectively and the user feels inconvenient.
