Abstract

턴테이블에 안착된 디스크의 편심을 보정하는 편심보정장치를 갖는 디스크 드라이브에 관한 내용이 개시되어 있다. 턴테이블 위에 안착된 디스크를 턴테이블의 회전 중심으로부터 소정 거리 이동시킬 수 있도록 턴테이블에 센터링을 설치하고 이 센터링을 편심보정부를 이용하여 적절이 이동시킬 수 있도록 하였다. 그 결과 디스크의 편심을 정밀하게 보정할 수 있어, 픽업이 하나의 정보 트랙에서 다른 정보 트랙으로 옮겨 정보를 기록하거나 재생할 때 트랙 추적 시간이 대폭 단축된다.Disclosed is a disc drive having an eccentricity correction device for correcting an eccentricity of a disc seated on a turntable. A centering was installed on the turntable so that the disk seated on the turntable could be moved a predetermined distance from the center of rotation of the turntable, and the centering could be properly moved by using an eccentricity compensator. As a result, disc eccentricity can be corrected accurately, so that track tracking time is greatly reduced when pickup is moved from one information track to another information track to record or play information.
