Abstract

본 발명은 하드디스크드라이브의 위치에러신호 검출방법에 관한 것으로서, 별도의 하드웨어가 필요없이 사용자가 위치에러장보를 용이하게 확인할 수 있도록 하기 위하여, 위치에러신호를 저장하기 위한 저장매체와 위치에러신호를 표시하기 위한 표시장치를 구비하고, 헤드에 의해 검출된 버스트신호를 이용하여 트랙추종을 수행하는 하드디스크드라이브의 위치에러신호 검출방법에 있어서; 트랙번호 및 위치에러신호 검출명령이 입력되면, 하드디스크의 소정트랙을 탐색한 후, 해당트랙에기록된 서보정보 중 버스트신호를 검출하는 제1과정; 상기 제1과정을 통하여 검출된 버스트신호를 이용하여 위치에러신호를 계산한 후, 계산된 위치에러신호를 상기 저장매체에 저장하는 제2과정; 및 하드디스크의 전체 서보정보가 검출 완료되면, 위치에러신호 검출명령이 종료되었음을 나타내는 소정인식신호를 발생시키고, 상기 저장매체로부터 위치에러신호를 검출하여 상기 표시장치에 표시하는 제3과정을 수행하도록 하였다.The present invention relates to a method of detecting a position error signal of a hard disk drive and, in order to enable a user to easily check a position error signal without requiring any additional hardware, a storage medium for storing a position error signal and a position error signal A method of detecting a position error signal of a hard disk drive having a display device for displaying a track signal by using a burst signal detected by a head, comprising: A first step of searching for a predetermined track on the hard disk and detecting a burst signal among the servo information recorded on the track when the track number and position error signal detection command is inputted; A second step of calculating a position error signal using the burst signal detected through the first process and storing the calculated position error signal in the storage medium; And a third step of detecting a position error signal from the storage medium and displaying the detected position error signal on the display device when the detection of the entire servo information of the hard disk is completed Respectively.
