Abstract

본 발명은 하드디스크 드라이브에서의 디펙트 처리방법에 관한 것이다.The present invention relates to a defect processing method in a hard disk drive.

본 발명은 번-인 테스트를 실행하여 에러가 발생되는 위치의 실린더, 헤드, 섹터 등에 대한 로그-인 리스트를 작성하는 단계; 상기 리스트에서 중복되는 섹터를 삭제하는 단계; 상기 리스트를 실린더, 헤드, 섹터의 순서대로 정리하는 단계; 상기 정리된 리스트로부터 순수한 디펙트 리스트를 작성하는 단계; 및 상기 순수한 디펙트 리스트를 이용하여 각 업체에 적합한 실제 디펙트 리스트를 작성하는 단계를 포함하여 된 하드 디스크 드라이브에서의 디펙트 처리방법에 있어서, 상기 리스트에서 중복되는 섹터를 삭제하는 단계와, 상기 리스트를 실린더, 헤드, 섹터의 순서대로 정리하는 단계 사이에 상기 리스트에 예상되는 디펙트 섹터를 추가로 등록하는 단계가 더 증설된다.The present invention includes a step of executing a burn-in test to create a log-in list for a cylinder, a head, a sector, etc. at a position where an error occurs; Deleting duplicate sectors from the list; Arranging the list in order of a cylinder, a head, and a sector; Creating a pure defect list from the sorted list; And creating an actual defect list suitable for each vendor by using the pure defect list, the method comprising: deleting a duplicated sector from the list; The step of additionally registering an expected defective sector in the list between steps of arranging the list in order of cylinder, head, and sector is further added.

따라서, 번-인 테스트 이후의 그로운 디펙트에 대해서도 대처할 수 있는 장점이 있다.Therefore, there is an advantage that it is possible to cope with the defect after the burn-in test.
