摘要： Method and apparatus for recording a plurality of audio channels on segmented tracks of a tape by rotary heads. The audio channels to be recorded are allocated to recording sectors provided for the individual audio channels on the basis of the relation between the number of the audio channels and the number of the segmented tracks, so that each recording track necessarily includes the individual audio channel recording sectors uniformly distributed in the longitudinal direction of the tape, and the two-dimensional distance between the sectors on which the same audio channel is recorded can be maximized on the tape. Thus, an adverse effect of an error attributable to a dropout and/or a scar formed on the tape can be dispersed, thereby achieving high capability for error correction.
