Abstract

본 발명은 광 정보기록 재생장치, 매체 및 기록재생방법에 관한 것으로, 디스크의 일정수의 트랙을 1블럭으로 구성하여 디스크 전체를 다수개의 블럭으로 구성하며, 각 블럭의 마지막 트랙에는 각 블럭내의 결함섹터에 대한 매핑정보가 기록되는 매핑섹터와 결함섹터를 대체할 대체섹터를 포함하는 제1매핑 영역을 형성하며, 디스크의 중간위치에는 제1매핑영역들에 대한 매핑정보가 기록될 영역과 대체섹터영역을 갖는 제2매핑영역을 형성함으로써 결함섹터를 효율적으로 처리할 수 있도록 하며, 시스템의 신뢰성을 향상시킬 수 있도록 한 것이다.The present invention relates to an optical information recording and reproducing apparatus, a medium, and a recording and reproducing method, wherein a predetermined number of tracks of a disc are composed of one block, and the entire disc is composed of a plurality of blocks, and the last track of each block has a defect in each block. A first mapping area including a mapping sector in which mapping information on the sector is recorded and a replacement sector to replace the defective sector, and an area in which the mapping information for the first mapping areas is to be recorded and a replacement sector in an intermediate position of the disc. By forming a second mapping region having an area, the defect sector can be efficiently processed and the reliability of the system can be improved.
