Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
광디스크재생장치에서 광픽-업의 트래킹 서보를 제어하는 회로에 관한 것이다.A circuit for controlling a tracking servo of an optical pick-up in an optical disc reproducing apparatus.
2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention
고속 트랙 서치시 트래킹 에러 출력에 발생하게 되는 임펄스 파형으로 인한 트래킹 발진을 방지할 수 있는 트래킹 서보제어회로를 제공한다.The present invention provides a tracking servo control circuit that can prevent tracking oscillation due to an impulse waveform generated at a tracking error output during a high-speed track search.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
고속 트랙 서치시 트래킹 에러 출력에 나타나는 설정된 레벨 이상의 임펄스 파형을 검출하여, 트래킹 에러 이득을 감소시킨다.The tracking error gain is reduced by detecting an impulse waveform above a set level appearing at the tracking error output during the high-speed track search.
4. 발명의 중요한 용도4. Important uses of the invention
광디스크재생장치의 트래킹 서보 제어회로에 이용한다.It is used in a tracking servo control circuit of an optical disc reproducing apparatus.
