ABSTRACT:
A digital signal recording apparatus includes first circuitry for forming digital video data, and second circuitry for forming digital audio data. Third circuitry is provided for forming (a) video synchronizing blocks each of which comprises a predetermined number of digital video data and synchronizing data, and (b) audio synchronizing blocks each of which comprises a predetermined number of digital audio data and synchronizing data. Recording circuitry is provided for recording the video synchronizing blocks and the audio synchronizing blocks in tracks formed on a recording medium, the tracks being generally aligned in the direction of travel in the recording medium. The recording circuitry includes time-division multiplexing circuitry for time-division multiplexing a predetermined number of video synchronizing blocks and a predetermined number of audio synchronizing blocks to produce a data sequence for each of the tracks. The time-divison multiplexing circuitry produces different data sequences for neighboring tracks.
