Abstract

본 발명은 하드 디스크의 디펙트 처리방법에 관한 것이다.The present invention relates to a defect processing method of a hard disk.

본 발명은 불량 섹터를 대치하기 위해 소정의 스페어 섹터를 두는 디펙트 처리방법에 있어서, 트랙당 1개의 스페어 섹터를 두지 않고 실린더의 맨 마지막 트랙에 소정 갯수의 스페어 섹터를 두는 한편, 설정된 스페어 섹터의 수보다 많은 수의 불량 섹터가 존재하는 경우의 불량 섹터를 처리하기 위해 불량 섹터 중 현재의 실린더에서 처리하지 못하는 불량 섹터는 가장 가까운 인접 실린더의 사용되지 않는 스페어 섹터에 재할당하여 처리하는 점에 그 특징이 있다.The present invention provides a defect processing method for placing a predetermined spare sector for replacing a defective sector, wherein a predetermined number of spare sectors are placed on the last track of the cylinder without placing one spare sector per track, In order to process a defective sector in which there are more defective sectors than the number of defective sectors, a defective sector which can not be processed in the current cylinder of the defective sector is reassigned to the unused spare sector of the closest adjacent cylinder, Feature.

이와 같이 트랙당이 아닌 실린더당 일정한 갯수의 스페어 섹터를 마련함으로써 스페어 섹터가 차지하는 크기를 줄일 수 있고, 재할당된 섹터를 가장 가까운 실린더의 스페어 섹터로 대치함으로써 재할당된 섹터를 판독/기록하기 위한 씨크 시간을 줄일 수 있다.In this way, by providing a predetermined number of spare sectors per cylinder rather than per track, it is possible to reduce the size occupied by the spare sector, and to read / write the reallocated sector by replacing the reallocated sector with the spare sector of the nearest cylinder You can reduce the seek time.

Description

하드 디스크의 디펙트 처리방법Defect handling method of hard disk

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제5도는 본 발명에 따른 하드 디스크의 디펙트 처리방법에 있어서, 실린더당 소정 갯수의 스페어 섹터를 둔 것을 나타내 보인 상태도.FIG. 5 is a state diagram showing a predetermined number of spare sectors per cylinder in the defect processing method of a hard disk according to the present invention. FIG.

제7도는 본 발명에 따른 하드 디스크의 디펙트 처리방법에 있어서, 스페어 섹터보다 많은 수의 불량 섹터가 존재할 경우 미처리된 불량섹터를 인접 실린더의 미사용 스페어 섹터에 재할당하는 것을 나타내 보인 상태도.FIG. 7 is a diagram illustrating a method of processing a defect of a hard disk according to the present invention, when an unprocessed bad sector is reallocated to an unused spare sector of an adjacent cylinder when there are more bad sectors than the spare sector.

Claims (2)

불량 섹터를 대치하기 위해 소정의 스페어 섹터를 두는 하드 디스크의 디펙트 처리방법에 있어서, 트랙당 1개의 스페어 섹터를 두지 않고 실린더의 맨 마지막 트랙에 소정 갯수의 스페어 섹터를 두는 것을 특징으로 하는 하드 디스크의 디펙트 처리방법.A defect processing method for a hard disk in which a predetermined spare sector is placed to replace a defective sector, characterized in that a predetermined number of spare sectors are placed on the last track of the cylinder without placing one spare sector per track . 설정된 스페어 섹터의 수보다 많은 수의 불량 섹터가 존재하는 경우의 불량 섹터를 처리하기 위한 하드 디스크의 디펙트 처리방법에 있어서, 상기 불량 섹터 중 현재의 실린더에서 처리하지 못하는 불량 섹터는 가장 가가운 인접 실린더의 사용되지 않는 스페어 섹터에 재할당하여 처리하는 것을 특징으로 하는 하드 디스크의 디펙트 처리방법.A defect processing method of a hard disk for processing a defective sector in a case where there are more defective sectors than the set number of spare sectors, characterized in that a defective sector which can not be processed by the current cylinder among the defective sectors And reallocating the spare sector to an unused spare sector of the cylinder for processing the defective sector of the hard disk. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
