Abstract

본 발명은 광 픽업 엑츄에이터에 관한 것으로서, 특히 대물렌즈 홀더가 와이어 서스펜션에 대해 포커싱 방향과 트랙킹 방향으로 동작할 때 포커싱 조정코일 및 트랙킹조정코일과 요크 플레이트의 외측 요크 내벽면에 설치된 영구자석사이에 발생되는 반발력으로 인해 요크 플레이트에 진동이 발생하여 광픽-업 액츄에이터의 떨림현상인 부공진이 발생하는 것을 방지한 광픽-업 액ㅌ츄에이터의 부공진 방지구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical pickup actuator, and in particular, between the focusing adjustment coil and the tracking adjustment coil and the permanent magnet installed on the inner yoke inner wall of the yoke plate when the objective lens holder operates in the focusing direction and the tracking direction with respect to the wire suspension. The anti-resonance structure of the optical pick-up actuator that prevents the generation of vibration in the yoke plate due to the repulsive force to prevent the negative resonance, which is a vibration phenomenon of the optical pick-up actuator.
