<p>PURPOSE:To realize an automatic reproduction of the video information accordant to an educational schedule, by recording each information segment with different distances shifted from an end of each track and obtaining a reproduction data with high reliability. CONSTITUTION:A program or data which is treated by a computer 3 is written and read with a video signal recorder/reproducer using a video tape. In this case, the same information segment is recorded to each of plural consecutive tracks A-C of a video tape which are formed with each field of the video signal. The different delay degress 1-3 are given to each of the same information segment from an end of each track to perform the recording. In such way, a data having high reliability can be extracted by using a majority logic which detects the coincidence between two data among three ones in the reproduction mode.</p> |
