A digital audio and video signal recording system and method wherein erasure of a channel has no major effect on adjoining audio signals in the case of high density recording. The same channel of audio signals are recorded arranged in blocks in a direction orthogonal to the helical track of the magnetic tape. There is a possibility of the occurrence of error at the two outside tracks due to narrowing of the tracks at the time of editing of a channel, but preferably an outer code is added to enable erasure correction.
