Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
본 발명은 하드 디스크 드라이브의 헤드에 관한 것으로, 특히 리드 갭 및 라이트 갭을 구비한 헤드를 이용하여 기록매체인 디스크상에 라이트된 데이타정보를 검증하는 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head of a hard disk drive, and more particularly to a method of verifying data information written on a disk, which is a recording medium, by using a head having a read gap and a write gap.
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
본 발명의 목적은 분리된 리드/라이트 갭을 사용하여 디스크상에 라이트되는 정보를 리드하여 이를 검증함으로서 데이타 라이트시 발생할 수 있는 라이트 폴트를 방지할 수 있는 방법을 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a method of preventing write faults that may occur during data write by reading and verifying information written on a disc using a separate read / write gap.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
별개의 리드 및 라이트 갭을 갖는 헤드를 구비하며, 상기 헤드의 리드채널과 라이트채널이 독립적으로 동작하는 하드 디스크 드라이브에 있어서, 외부장치로부터 데이타 라이트 명령이 있을 경우 이에 응답하여 외부장치로부터 수신된 데이타정보를 버퍼에 저장한 후 상기 라이트 갭을 통하여 디스크상에 라이트한다. 이와 동시에 상기 라이트 갭 후위에 위치한 리드 갭을 통하여 상기 디스크상에 라이트된 데이타를 리드하여 이를 상기 버퍼에 저장된 데이타와 비교한다. 상기 비교결과 데이타가 같을 경우 외부장치로 데이타 라이트의 완료를 보고하며, 상기 비교결과 데이타가 다를 경우 할당된 예비섹터에 데이타를 라이트한다. 만약 할당된 예비섹터가 없는 경우 라이트 폴트를 외부장치로 보고한다.A hard disk drive having a head having separate read and write gaps, wherein the read channel and the write channel of the head operate independently, the data received from the external device in response to a data write command from the external device. The information is stored in a buffer and then written onto the disk through the write gap. At the same time, the data written on the disk is read through the read gap located behind the write gap and compared with the data stored in the buffer. When the comparison result data is the same, the completion of data write is reported to an external device. When the comparison result data is different, the data is written to the allocated spare sector. If no spare sector is allocated, the write fault is reported to the external device.
4. 발명의 중요한 용도4. Important uses of the invention
하드 디스크 드라이브에 유용히 사용될 수 있다.This can be useful for hard disk drives.
