ABSTRACT:
A video disc playback apparatus for recovering signal from disc records having radially aligned information fields is provided with multiple signal recovery transducers for interactive signal playback. The signal recovery transducers are independently translated to information fields having like synchronization signal components responsive to player program controls and recovered track identification signals. Synchronization signal components recovered by the various transducers are compared to generate an error signal for activating further transducer means to translate the signal recovery transducers tangentially along the prerecorded information tracks and thereby adjust the relative angular location of the signal recovery transducers to reduce the phase differential of the synchronization components of signal between the respective signals and thereby precluding the need for independent frame synchronization apparatus.
