Abstract

본 발명은 광픽업장치에 관한 것으로, 픽업엑츄에이터와 픽업베이스로 이루어지는 광픽업장치에 있어서, 상기 픽업엑츄에이터를 구성하는 서스펜션의 설치방향 반대쪽의 대물렌즈홀더와 외측요오크판 사이에 반경방향으로 장력이 걸릴 수 있도록 외측으로 만곡진 형상으로 고무댐퍼를 끼워 설치하는 한편, 요오크플레이트의 외곽을 원형으로 형성하고, 상기 요오크플레이트가 안착되는 픽업베이스상면에 상기 요오크플레이트의 곡률반경과 동일한 곡률반경을 갖는 원형의 안착홈을 형성하여 엑츄에이터의 구동특성을 향상시키고, 픽업베이스에 대한 엑츄에이터의 자세조성작업성을 향상시킬 수 있도록 한 것이다.
