ABSTRACT:
A stylus position detecting apparatus in use for a video disc player using a disc of the groove type, detecting plates for detecting leakage components of a high frequency signal supplied from a high frequency signal source and flowing through a flylead, and for reading out a recorded signal in a disc are provided on both sides of the flylead. The leakage signal components detected by the detecting plates are detected to positive and negative directions with respect to a reference voltage. These voltages obtained by the detections are added by an adder, to find a stylus position.
