Abstract

본 발명은 결함섹터가 있는 광자기디스크를 기록 및 재생하기 위하여 억세스하는 방법에 관한 것으로, 일군의 논리적 어드레스의 선두 어드레스에 해당하는 영역을 찾는 탐색(SEEK)단계와 탑색단계에서 찾은 영역이 제1결함목록(PDL)이나 제2결함목록(SDL)에 등록된 영역이면 소정섹터만큼 스킵하는 스킵단계와 탕색한 영역을 기록 및 재생하는 기록 및 재생단계와 일군의 논리적인 어드레스 영역 중 정상적인 영역에 대한 기록 및 재생이 완료되면, SDL에 등록된 교체영역을 탐색하는 교체영역 탐색단계와 탐색한 교체영역을 기록 및 재생하는 교체영역 기록 및 재생단계를 구비하여 PDL과 SDL에 등록된 결함섹터가 있는 광자기 디스크를 일군위 논리적 어드레스에 대응하는 물리적 어드레스로 억세스한다.The present invention relates to an access method for recording and reproducing a magneto-optical disc with defective sectors, wherein a search (SEEK) step for finding an area corresponding to the head address of a group of logical addresses and a region found in the top color step are the first. If the area is registered in the defect list PDL or the second defect list SDL, a skip step of skipping a predetermined sector, a recording and reproducing step of recording and reproducing a colored area, and a normal area of a group of logical address areas are performed. When recording and reproducing are completed, a replacement area searching step of searching for a replacement area registered in the SDL and a replacement area recording and reproducing step of recording and reproducing the searched replacement area include optical areas with defective sectors registered in the PDL and SDL. The magnetic disk is accessed with a physical address corresponding to a group of logical addresses.
