ABSTRACT:
A magnetic recording and reproducing system encodes a digitized audio signal into first and second blocks which are constituted by sample of the audio signal within one field or one frame of a video signal in a sequence dependent on a field frequency of the video signal so that the encoding is completed in each block and all of the samples of the audio signal within one field or one frame are encoded in a predetermined number of the first and second blocks. The first block is constituted by a number of samples greater than a number of samples constituting the second block. The digital audio signal is recorded on and reproduced from a magnetic tape together with the video signal, and all of the samples of the audio signal within one field or one frame are obtained to reproduce the original analog audio signal by decoding each block with reference to the identification signal.
