Abstract

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

본 발명은 읽기용 갭과 쓰기용 갭의 옵셋(Offset)을 위해 서스펜션에 편위각(Skew)을 갖고 부착되는 하드디스크 드라이브의 자기저항 헤드 장치에 관한 것이다.The present invention relates to a magnetoresistance head device of a hard disk drive having a skew attached to a suspension for offsetting a read gap and a write gap.

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

본 발명은 읽기 및 쓰기 트랙 폭 간의 차이를 최소화하여 TPI를 증가시키고, 오프-트랙의 가능성을 최소화 함으로써 고용량/고밀도화에 대응할 수 있도록 하는 헤드 장치를 제공하는데 있다.The present invention provides a head device capable of increasing the TPI by minimizing the difference between the read and write track widths and minimizing the possibility of off-track so as to cope with high capacity / high density.

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

본 발명은 통상의 MR 헤드 장치에 있어, TPI를 증가시키고 고용량/고밀도화에 대응하기 위하여, 드라이브가 가지고 있는 스큐(Skew)의 중심값을 기준으로 하여 헤드 장치를 서스펜션에 스큐를 주어 부착시킴으로써 오프-트랙의 가능성을 최소화 하고, 읽기 트랙 폭과 쓰기 트랙 폭 간의 차이를 최소화 할 수 있도록 한다.In order to increase the TPI and to cope with high capacity / high density in the conventional MR head device, the head device is skewed and attached to the suspension based on the center value of the skew held by the drive, Minimize the possibility of the track, and minimize the difference between the read track width and the write track width.

4. 발명의 중요한 용도4. Important Uses of the Invention

본 발명은 헤드 스큐에 의해 실제적으로 디스크 면상에 데이타가 쓰여질때 유효 트랙폭과 읽기 유효 트랙폭은 근접하게 되고, 오프-트랙의 가능성을 줄임으로 그만큼 동일 조건하에는 트랙밀도(TPI)를 증가시킬 수 있음에 따라 하드디스크 드라이브의 고용량/고밀도화를 가져오게 되는 효과가 있다.In the present invention, when the data is actually written on the disk surface by the head skew, the effective track width and the read effective track width become close to each other, and the possibility of off-track is reduced, thereby increasing the track density TPI It is possible to increase the capacity and density of the hard disk drive.
