ABSTRACT:
In a tracking servo system of a recording-disc information reading and reproducing apparatus such as a video disc player, a tracking error signal indicative of an amount of deviation of an information pickup medium such as a focused spot of a scanning beam of light from a target track of the recording disc being scanned is amplified with a gain which is varied as the pickup medium is displaced radially of the recording disc between an outer peripheral area and a central area of the disc.
