Abstract

디스크드라이브에 설치된 픽업을 디스크의 반경방향으로 안내하기 위한 디스크드라이브의 픽업 안내장치에 관한 내용이 개시되어 있다. 스핀들모터와 턴테이블의 조립오차, 디스크 자체의 편심 또는 휨오차, 베이스의 휨에 의한 픽업조립체의 기울임 오차를 보정할 수 있는 디스크드라이브의 픽업 안내장치를 제공하는데 목적이있다. 이를 위하여, 가이드축의 적어도 일단에 형성되어 가이드축의 축 중심과 다른 축 중심을 갖는 편심축을 만들고, 편심축을 베이스프레임에 회전가능하게 설치하여 편심축을 회전시켜 기울기를 조정할 수 있도록 하였다.Disclosed is a pickup guide apparatus for a disc drive for guiding a pickup installed in the disc drive in a radial direction of the disc. It is an object of the present invention to provide a pickup guide device for a disc drive that can correct an error in assembling the spindle motor and the turntable, an eccentricity or a bending error of the disc itself, and a tilting error of the pickup assembly due to the bending of the base. To this end, an eccentric shaft is formed on at least one end of the guide shaft to have an axial center different from the axial center of the guide shaft, and the eccentric shaft is rotatably installed on the base frame to adjust the inclination by rotating the eccentric shaft.
