Abstract

PURPOSE:To use conventional and less expensive disc recorder mechanism such as floppy disc, by providing scan converter, FM modulation circuit, FM demodulation circuit, clock pulse recording and playback circuit, and luminance variance compensation circuit and the like. CONSTITUTION:The output of a scan converter SC which extends the time axis of a video signal to be recorded and the output of a clock pulse generating circuit for scan convert CG are written in a floppy disc FDD at the same time. At playback, an FM demodulation output of playback clock pulse and the playback video signal output are in differential amplification DF to cancel the luminance variation component of the playback video signal, and the output is in scan convert with a clock pulse in synchronizing with the playback clock pulse to restore the time axis to the original value, allowing to obtain the playback video signal.
