Abstract
A tangential servo control signal generating device for a device for reproducing recorded data from a video disc for controlling the movement of a pick-up in the tangential direction of the video disc. A color burst signal is inverted in phase for every other period of a regenerative horizontal synchronizing signal. This signal is gated by a detection signal the timing of which is determined by the occurrence of the predetermined reference point on the waveform of the color burst signal. An error signal is generated in accordance with the phase or timing difference between the detection signal and the occurrence of the predetermined reference signal which is used to form a tangential servo control signal.
