Abstract

PURPOSE:To switch automatically for an operation mode of a video disc, through a repetitive playback instruction, by providing a start address registrating means and a repetitive playback instruction means, and detecting the coincident point of the address information stored with a specific means. CONSTITUTION:A synchronizing signal separation circuit 20 separates a composite synchronizing signal from a luminance signal transmitted from a video signal processing circuit 13. A counter 21 is reset with a signal of a vertical synchronizing separation circuit 22, and a gate pulse opening a gate circuit 23 at the 17th H of the vertical blanking period where the address information of a recording track is recorded, is introduced. The address information from the gate circuit 23 is given to a data latch circuit 27 and renewed every time when a pickup 10 reads the address information. A control device 18 includes a CPU, executes an operation program through the instruction of the control key 19, a pulse signal is applied to a tracking servo circuit 15, and the switching of fast feed and play mode can be made automatically and simply.
