Abstract

PURPOSE:To immediately display a reproduced image without any drifting in synchronization by supplying to a monitor a video signal including a composite synchronizing signal while keeping in-phase with the vertical phase of reproduction during accessing to a track. CONSTITUTION:When switching a black burst signal BB to a reproduced signal PB upon completion of an access to a track, a reference synchronization generator 4 is reset with the phase of a reproduced horizontal synchronizing signal immediately before the switching. In result of this reset, the horizontal phase of a reference synchronizing signal REF is obtained upon the completion of the track-accessing, and made synchronize with the horizontal phase of the reproduced signal. Thus the horizontal phase of a black burst signal is synchronized with a reproduced signal immediately before the switching from the black burst signal BB to the reproduced signal PB. Therefore, there occurs no H-skew in a picture immediately after the switching, that is, the switching is executed extremely stably.
