Abstract

본 발명은 다이나믹 업소버를 갖는 광픽업 액츄에이터에 관한 것으로서, 크게 변위되는 렌즈홀더에 댐피홈을 형성하고 구형 금속볼인 다이나믹 업소버를 상기 댐핑홈에 넣어 실리콘 겔등의 댐핑재로 충진시킴으로써 저주파 및 고주파를 동시에 불요공진억제시키는 광픽업 액츄에이터에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical pickup actuator having a dynamic absorber, wherein a damping groove is formed in a lens holder that is greatly displaced. The present invention relates to an optical pickup actuator that suppresses unwanted resonance.
