ABSTRACT:
A digital servo circuit for an optical disk player having a tracking actuator utilizes a digital filter for alternately extracting from a tracking error signal a frequency component within a specified band and a high-frequency component. In response to the high-frequency component, a braking force is applied to the tracking actuator when a brake ON command is issued. Coefficient values in the digital filter are set up depending on whether the brake ON command is issued.
