Abstract

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

본 발명은 하드디스크 드라이브에 관한 것으로, 특히 버퍼 메모리를 이용하여 고속 데이타 액세스를 구현할 수 있는 방법에 관한 것이다.The present invention relates to a hard disk drive, and more particularly, to a method for implementing high-speed data access using a buffer memory.

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

배드섹터를 원인으로 발생될 수 있는 데이타 액세스 타임을 최소화시킬 수 있는 고속 데이타 액세스방법을 제공함에 있다.Speed data access method capable of minimizing a data access time that may occur due to a bad sector.

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

하드 디스크 드라이브의 고속 데이타 액세스 방법에 있어서, 디스크상의 메인터넌스 영역에 라이트되어 있는 디펙테이블을 리드하여 배드섹터에 대응되는 대치섹터의 위치를 검출하는 대치섹터 위치검출과정과, 상기 검출된 대치섹터에 기록되어 있는 데이타를 버퍼 메모리에 저장하는 데이타 저장과정과, 호스트컴퓨터와 같은 외부장칠호부터 데이타 리드 명령이 수신되는 경우 해당 배드섹터에 대응되는 대치섹터의 데이타를 상기 버퍼 메모리로부터 리드하여 호스트컴퓨터로 전송하는 데이타 전송과정으로 이루어짐을 특징으로 한다.A high-speed data access method for a hard disk drive, comprising: a replacement sector position detection step of reading a defective table written in a maintenance area on a disk to detect a position of a replacement sector corresponding to a bad sector; And when a data read command is received from an external device such as a host computer, data of a replacement sector corresponding to the bad sector is read from the buffer memory and transferred to the host computer And a data transmission process.

4. 발명의 중요한 용도4. Important Uses of the Invention

하드 디스크 드라이브의 고속 데이타 액세스방법에 사용될 수 있다.Speed data access method of a hard disk drive.
