ABSTRACT:
Disclosed is a magnetic recording-playback apparatus suitable for recording and reproducing a signal including a broad-band composite video signal and a method therefor. The broad-band signal is time-sliced into signals in two channels, and each divided signal is expanded on the time axis so that it is converted into a lower-band signal before being recorded on a magnetic tape. In the time axis expansion process, the vertical blanking signal and/or horizontal blanking signal is not expanded, whereby the divided video signals have a still lower frequency band.
