Abstract

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

하드 디스크 드라이브의 디펙 섹터 처리방법에 관한 것으로, 특히 데이타 섹터에 디펙이 발생하는 경우 이를 처리하기 위한 방법에 관한 것이다.And more particularly, to a method for processing a defective sector in a data sector.

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

디스크 기록매체상의 데이타 섹터에 디펙이 발생하는 경우 디펙이 발생한 섹터의 기록된 데이타의 유실을 막을 수 있는 디펙 섹터 처리방법을 제공함에 있다.And it is an object of the present invention to provide a defective sector processing method capable of preventing loss of recorded data of a sector in which a defective sector occurs when a defective sector occurs in a data sector on a disk recording medium.

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

하드 디스크 드라이브의 디펙 섹터 처리방법에 있어서, 호스트로부터 데이타 리드 혹은 라이트 명령이 수신되는 경우 이에 응답하여 상기 수신된 목적 테이타 섹터의 어드레스가 소속되는 존을 계산하는 과정과, 상기 검색용 테이블을 통해 상기 디펙 테이블로부터 상기 계산된 존의 오프셋을 취득하는 과정과, 상기 목적 데이타 섹터 어드레스가 디펙 테이블상의 어드레스보다 작을때까지 상기 목적 데이타 섹터 어드레스를 한 섹터분씩 증가시켜 디펙 테이블상의 어드레스를 검색하는 과정과, 상기 검색결과 목적 데이타 섹터 어드레스가 디펙테이블상의 어드레스보다 작을 경우 해당 목적 데이타 섹터 어드레스에 수신된 데이타를 리드 혹은 라이트 하는 과정으로 이루어 짐을 특징으로 한다.A method for processing a defective sector of a hard disk drive, the method comprising the steps of: calculating a zone to which an address of the received target sector belongs in response to a data read or write command received from a host; Obtaining an offset of the calculated zone from the decipher table; and increasing the sector number of the target data sector by one sector until the target data sector address is smaller than the address on the decipher table, And reading or writing the data received at the target data sector address when the target data sector address of the search result is smaller than the address on the defective table.

4. 발명의 중요한 용도4. Important Uses of the Invention

하드 디스크 드라이브의 데이타 섹터 운용에 사용될 수 있다.And can be used for data sector operation of the hard disk drive.

Claims (2)

하드 디스크 드라이브의 디펙 처리방법에 있어서, 호스트로부터 데이타 리드 혹은 라이트 명령이 수신되는 경우 이에 응답하여 상기 수신된 목적 데이타 섹터의 어드레스가 소속되는 존을 계산하는 과정과, 상기 검색용 테이블을 통해 상기 디펙 테이블로부터 상기 계산된 존의 오프셋을 취득하는 과정과, 상기 목적 데이타 섹터 어드레스가 디펙 테이블상의 어드레스보다 작을 때까지 상기 목적 데이타 섹터 어드레스를 한 섹터분씩 증가시켜 디펙 테이블상의 어드레스를 검색하는 과정과. 상기 검색 결과 목적 데이타 섹터 어드레스가 디펙테이블상의 어드레스보다 작을 경우 해당 목적 테이타 섹터 어드레스에 수신된 데이타를 리드 혹은 라이트 하는 과정으로 이루어짐을 특징으로 하는 하드 디스크 드라이브의 디펙 섹터 처리방법.A method for processing a defective area in a hard disk drive, the method comprising: calculating a zone to which an address of the received target data sector belongs in response to receiving a data read or write command from the host; Acquiring an offset of the calculated zone from the table; and increasing the target data sector address by one sector until the target data sector address is smaller than the address on the defective table, thereby searching for an address on the defective table. And reading or writing the data received at the target sector address when the target sector address of the search result is smaller than the address of the target sector. 제1항에 있어서, 상기 디스크 미디어상에 구획되어 있는 각 존에는 미할당된 여유 섹터가 구비되어 있는 것을 특징으로 하는 하드 디스크 드라이브의 디펙 섹터 처리방법.The method of claim 1, wherein unassigned spare sectors are provided in each zone partitioned on the disk media. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
