ABSTRACT:
Methods and apparatus are provided for recording and reproducing digital information signals including image and audio portions in successive tracks on a magnetic tape. An ID signal is produced for one of an image portion and an audio portion of a corresponding digital information signal to be recorded. The ID signal indicates whether the portion is to be after-recorded in a respective track. The ID signal is combined with the portion to form a recording signal. Previously recorded digital information signals are reproduced from the track and an ID signal thereof is obtained. The recording of the portion in the track is controlled based on the reproduced ID signal.
