Abstract
In an apparatus for recording and/or reproducing digital audio and video signals in slanted tracks on a magnetic tape, an integral number of samples of the digital audio signals, which forms a unit thereof, are allocated to a plurality of fields of the digital video signals. Sequence signals are recorded in both slanted and longitudinal tracks on the tape. The sequence signals indicate the conclusion of the digital audio data, that is, the units of the digital audio signals on the basis of the fields of the digital video signals. During reproduction of the sequence signals, the error rate of the sequence signals reproduced from the slanted and longitudinal tracks, respectively, are detected. Based on the detected error rate, the sequence signals reproduced from either the slanted tracks or the longitudinal tracks are selected. Therefore, if the sequence signals are lost or distorted on either the slanted or longitudinal tracks, the sequence signals may be still reproduced from the other track.
