Abstract

본 발명은 컴팩트 디스크의 자동 포커싱 방법에 관한 것으로, 디스크의 데이타 리드시 손상된 트랙을 만나 근접트랙을 읽으려해도 근접트랙도 손상되어 읽을 수 없을 경우 자동으로 다음곡으로 점프하며 읽을 수 없는 곡은 메모리하여 다음번의 플레이시 이 메모리된 곡은 스킵하도록 함으로써 디스크에 손상된 부분이 있어 일정 부분의 데이타를 읽을 수 없는 경우에도 디스크의 배출 없이 계속해서 플레이 동작이 수행되도록 한 것이다.The present invention relates to an automatic focusing method of a compact disc. When a disc is read, a proximity track is damaged and a proximity track is damaged even if the proximity track is damaged and cannot be read. The next time you play, the memorized song is skipped, so that even if there is a damaged part of the disc and some data cannot be read, the play operation continues without ejecting the disc.
