자기 디스크 드라이브의 트랙 오프세트 보정방법Track Offset Correction Method for Magnetic Disk Drives

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 고정형 자기 기록장치의 대략 구성도,1 is a schematic configuration diagram of a fixed magnetic recording apparatus according to the present invention;

제2도는 자기 기록장치의 제어 블록도,2 is a control block diagram of a magnetic recording apparatus;

제3도는 트랙 오프세트에 따른 서보 데이타의 자기헤드 신호크기를 보인 설명도.3 is an explanatory diagram showing magnetic head signal sizes of servo data according to track offsets.

자기 디스크 드라이브의 기록장치에 있어서, 디스크의 인덱스 구간(Index)를 3등분하고, 각 트랙의 종류(3N, 3N+1, 3N+2)에 따라 인덱스 구간(Index)의 해당부분에 서보 데이타신호를 기록하며, 엔코더를 사용하여 자기 헤드를 해당트랙의 중심에 위치시킬 때 온도에 기인한 트랙의 오프세트에 의해 자기헤드로부터 독출(Read)되는 각 부분(A,B,C)의 서보 데이타량에 따라 자기헤드를 트랙의 중심방향으로 이동할 수 있게 함을 특징으로 하는 자기 디스크 트랙 오브세트 보정방법.In the recording apparatus of a magnetic disk drive, the index section (Index) of the disk is divided into three, and the servo data signal is applied to the corresponding section of the index section (Index) according to the type (3N, 3N + 1, 3N + 2) of each track. The servo data amount of each part (A, B, C) read from the magnetic head by the offset of the track due to the temperature when the magnetic head is positioned at the center of the track using the encoder. And moving the magnetic head toward the center of the track. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
