Abstract

1. 청구범위에 기재된 발명이 속한 분야1. Fields to which the invention described in the claims belong

하드디스크 드라이브 헤드스큐(Head Skre)최적화 방법에 관한 것임.Hard disk drive head skew optimization method.

2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention

디스크 개개별로 변형사의 스큐값을 제서, 각 드라이브별로 다른 스큐값을 갖도록 하는 방법을 생산되는 전체 드라이브의 성능화 품질을 균일하게 유지할 수 있는 방법을 제공함.By providing the skew value of the twisted yarn of each disk, it is possible to have a different skew value for each drive, and to provide a method of maintaining the performance quality of the entire drive uniformly.

3. 발명의 해결 방법의 요지3. Summary of the Solution of the Invention

디스크 드라이브의 헤드스큐 최적화 방법에 있어서, 상기 디스크 드라이브의 헤드스큐없이 포멧하여 존(Zone)번호 및 헤드번호를 초기화하고 현재 헤드의 마지막 섹터부터 다음 헤드의 첫번째 섹터까지 서치하는 제1과정과, 상기 제1과정에서 서치하는 헤드 트랙 스큐를 저장 및 계산하여 헤드 번호를 증가시키고 제2과정과, 상기 제2과정에서 카운트 상기 헤드 번호가 마지막 헤드인가를 검출하는 제3과정과, 상기 제3과정에서 마지막 헤드 일때 트랙 N에 있어 마지막 헤드의 마지막 섹터로부터 트랙 N+1에 있어 첫번째 헤드의 첫번째 섹터를 서치하는 제4과정과, 상기 제4과정에서 서치하는 값으로부터 실린더 스큐를 계산하는 제5과정과, 상기 제5과정과에서 계산한 스큐값으로부터 존 번호를 카운트하는 존이 마지막 존인가를 계산하여 마지막 존일때 정보보관관리를 위해 사용되는 실린더의 각존을 위해 전체 헤드스큐 값을 저장하고 헤드스큐 값을 저장마고 헤드스큐로 포멧팅하는 제3과정으로 이루어짐을 특징으로 하는 디스크 드라이브에 있어서 헤드스큐 최적화 방법.A head drive optimization method of a disk drive, comprising: a first process of initializing a zone number and a head number by formatting without a head skew of the disk drive and searching from the last sector of the current head to the first sector of the next head; Storing and calculating the head track skew searched in the first step to increase the head number, and in the second step, counting in the second step detecting whether the head number is the last head, and in the third step A fourth step of searching for the first sector of the first head in the track N + 1 from the last sector of the last head in track N when the last head, and a fifth step of calculating cylinder skew from the value searched in the fourth process; When the zone counting the zone number is the last zone from the skew value calculated in the fifth step, it is determined that the zone is the last zone. Head skew optimization method for gakjon the cylinder skew value and store the entire head in the disk drive, characterized by a third step of putting constituted by any storage format in Margot head skew the head skew value that is used for storage management.
