ABSTRACT:
A continuous both-side playback type video disc apparatus having an external command signal generator for generating an external command signal to an external recorder in response to a playback start signal or a lead-in or lead-out track detection signal obtained from a signal reading head, and also an external command signal output terminal for supplying the external command signal therefrom. Synchronized operation control is executed in such a manner that, upon completion of playing back one side of a disc, the recording operation of the external recorder is temporarily brought to a halt by a pause signal at the instant of detection of the lead-out track by the signal reading head, and after proceeding to playback of the other side of the disc, the recording operation is resumed at the instant of detection of the lead-in track on the other side of the disc by the signal reading head. The known operational intricacy in a dubbing mode can be diminished, and the conventional drawbacks are eliminated, including inclusive of partial signal dropouts induced in proceeding from one side of the disc to the other side and also any wasteful recording space that may otherwise result from the existence of no-signal portions.
