Abstract

턴테이블에 안착되는 디스크의 편심을 방지하는 디스크 편심방지기능 갖는 디스크드라이브에 관한 내용이 개시되어 있다. 디스크 편심방지구조를 갖는 디스크드라이브는 베이스프레임에 설치된 스핀들모터의 축에 압입되어 회전하는 턴테이블과, 스핀들모터의 축에 압입되어 턴테이블 위에 설치되는 허브와, 허브에 삽입되도록 센타홀이 형성된 디스크와, 허브에 설치되어 디스크의 편심을 보정하며 편심이동을 방지하는 편심방지수단을 구비하는 것을 특징으로 한다. 그 결과, 편심방지수단이 디스크가 편심 이동하는 것을 방지하며, 편심방지수단을 구성하기 위한 부품 수를 줄여 생산원가를 줄일 수 있다.Discloses a disc drive having a disc eccentricity preventing function for preventing eccentricity of a disc that is seated on a turntable. A disc drive having a disc eccentricity preventing structure includes a turntable which is press-fitted into a shaft of a spindle motor provided in a base frame and rotates, a hub press-fitted into a shaft of the spindle motor and installed on a turntable, And eccentricity preventing means provided on the hub for correcting the eccentricity of the disk and preventing eccentric movement. As a result, the eccentricity preventing means prevents eccentric movement of the disk, and the number of parts for constituting the eccentricity preventing means can be reduced, thereby reducing the production cost.

Description

디스크 편심방지구조를 갖는 디스크드라이브Disk drive with disk eccentricity prevention structure

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제3도는 본 발명에 따른 디스크 편심방지구조를 갖는 디스크드라이브의 주요뷰룰 도시한 사시도이다. 제4도는 본 발명에 따른 디스크 편심방지구조를 갖는 디스크드라이브이 허브를 확대하여 도시한 반단면도이다. 제5도는 제4도의 디스크가 턴테이블에 안착된 상태를 도시한 반단면도이다.FIG. 3 is a perspective view showing a main view of a disk drive having a disk eccentricity preventing structure according to the present invention. FIG. FIG. 4 is an enlarged half sectional view of a disk drive hub having a disk eccentricity preventing structure according to the present invention. FIG. 5 is a half sectional view showing a state in which the disk of FIG. 4 is seated on the turntable.

Claims (4)
