Abstract

PURPOSE: In case the information signal does not exist or is deteriorated, the recording medium is controlled accurately by switching the velocity control unit as in case the information signal exisis. Thus the video circuit is cut off for a fixed period of time when no signal existence is detected, thus the picture image being reproduced immediately.
