Abstract

본 발명은 리드 인 영역에 에러가 발생한 경우에도 리드 인 영역의 정보를 읽어내고자 한 광디스크 리드 인 영역 정보판독 방법에 관한 것이다.The present invention relates to an optical disc lead-in area information reading method for reading information of a lead-in area even when an error occurs in the lead-in area.

이러한 본 발명은 전원이 공급되면 픽업을 최내주로 이동시키고 픽업이 리드 인 영역으로 이동되면 리드 인 영역의 정보를 판독하는 제1과정과; 판독되는 리드 인 영역의 정보가 정상적으로 모두 판독되면 그 리드인 영역의 정보를 메모리에 저장하는 제2과정과; 리드 인 영역의 판독중 에러가 발생되면 기설정된 트랙만큼 외주방향으로 트랙 점프를 실시한 후 리드 인 영역의 정보를 판독하는 제3과정을 순차 실행시키게 되는 것이다.The first aspect of the present invention includes a first step of moving the pickup to the innermost periphery when power is supplied and reading information of the lead-in area when the pickup is moved to the lead-in area; A second step of storing the information of the lead-in area in a memory when information of the lead-in area to be read is normally read; A track jump is performed in the outer circumferential direction for a predetermined number of tracks when an error occurs during reading of the lead-in area, and then the information of the lead-in area is read out.
