Abstract
An audio signal of arbitrary length is recorded on a single track of a magnetic disk, and a plurality of corresponding or associated video signals are recorded on successive coaxial tracks. The deviation of each video signal is counted during the reception of the audio signal, and data representative thereof is superposed on the recorded video signals to 'coordinate' subsequent playback.
