Abstract
Digitalized audio signals of a plurality of channels are stored blockwise in each channel and then recorded blockwise in repeating channel sequence in similarly situated portions of successive oblique tracks in which are also recorded concurrent video signals, but the recording of a channel block is skipped once per picture field, so that an integral number of channel sequences will record all the audio channel information for a period equal to a picture field. In the video track where audio recording is skipped, other information may be recorded. The read-out rate of the channel blocks is slightly accelerated so that the track skipping loses no information. Consequently, the recorded signals can be cut in, or cut off, or edited at any frame end without loss of registry of the audio channels.
