Abstract

1. 청구벙위에 기재된 발명이 속한 기술분야1. Description of the invention

하드 디스크 드라이브의 메인터넌스정보 복구방법에 관한 것이다.And a method of restoring the maintenance information of the hard disk drive.

2. 발명이 해결하려고 하는 기술적 과제2. Technical Challenges to be Solved by the Invention

메인터넌스영역에 기록된 메인터넌스정보가 손상되는 경우에도 이를 복구할 수 있는 방법을 제공함에 있다.There is provided a method of recovering maintenance information recorded in a maintenance area even if the maintenance information is damaged.

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

제조공정시 메인터넌스정보를 메인터넌스영역 이외의 트랙에 재기록한후 상기 메인터넌스영역에 기록된 메인터넌스정보 리드에러발생시마다 상기 메인터넌스영역 이외의 트랙으로부터 상기 정보를 리드함을 특징으로 한다.In the manufacturing process, the maintenance information is rewritten to a track other than the maintenance area, and the information is read from a track other than the maintenance area each time a maintenance information read error recorded in the maintenance area occurs.

4. 발명의 중요한 용도4. Important Uses of the Invention

하드 디스크 드라이브의 메이터넌스정보 관리에 사용될 수 있다.And can be used for management of the management information of the hard disk drive.
