Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. Technical field to which the invention described in the claims belongs

하드 디스크 드라이브에 있어서ㅢ 번-인 테스트.Burn-in test for hard disk drives.

2. 발명이 해결하고자 하는 기술적 과제2. Technical Problems to be Solved by the Invention

하드 디스크 드아리브에 있어서 번-인 테스트 시간 단축 및 에러 발생율을 낮추고자 한다.We want to shorten the burn-in test time and reduce the error rate in hard disk drive ribs.

3. 발명의 해결방법의 요지3. The point of the solution of the invention

번-인 테스트 중간에 한번 발생한 디펙위치를 기록해 둠으로써 한번 검출된 디펙은 더 이상 테스트를 하지 않게 한다.By recording the location of the defec- tions that occurred once during the burn-in test, the detected defects will no longer be tested.

4. 발명의중요한 용도4. Important Uses of the Invention

하드 디스크 드라이브 번-인 테스트.Hard disk drive burn-in test.
