Abstract
A videodisc playback system is disclosed which enables repeated reproduction of signals recorded on a videodisc. The system comprises the usual means to mount and rotate the videodisc to be played back and a shifting device that shifts the scanning position of a read-out device in a radial direction of the videodisc. A tracking control device controls the shifting device so that the scanning position of the read-out device is on the track. Further, the system includes fast playback circuitry which causes fast playback of the videodisc by shifting playback tracks N multiple number of times, one track at a time to the next adjacent track, during one revolution of the videodisc. Repeated reproduction of signals is accomplished by circuitry connected to the fast playback circuitry that causes a predetermined number of tracks to be repeatedly played back, the predetermined number being an integral number of N.
