Abstract
본 발명은 컴팩트 디스크 플레이어의 디스크 편심 보상장치에 관한 것으로, 검출된 편심량이 일정치 이상으로 나타날 때 트랙킹액튜에이터 구동신호의 위상을 보상하기 위한 수단 및 슬라이드모터 구동신호의 이득을 보상하기 위한 수단을 구비하여 마이컴의 제어에 따라 선택적으로 보상함으로써, 트랙킹 제어 루프 상의 외란과 내란의 문제를 해결하고 이득 설정을 쉽게하고 디스크 드라이버의 트랙킹 서보속도를 향상 시키기 위한 것이다.The present invention relates to a disc eccentricity compensation device of a compact disc player, comprising a means for compensating for the phase of a tracking actuator drive signal when the detected eccentricity appears above a certain value and a means for compensating for the gain of the slide motor drive signal. By selectively compensating according to the control of the microcomputer, the problem of disturbance and disturbance on the tracking control loop is solved, the gain setting is easy, and the tracking servo speed of the disk driver is improved.
