ABSTRACT:
Disclosed is a video signal recording system, in which the input video signal is rid of unneeded portions, transformed on the time axis and divided into n channels so that they are recorded in a bandwidth narrower than 1
of original one. The system also enhances the latitude in choosing a clock frequency for time-axis conversion and a track width, thereby optimizing the picture quality and recording time length on a trade-off basis.
