Abstract
본 발명은 와이어타입 광픽업 액츄에이터의 이물 대물렌즈에 관한 것으로서 서보시스템에서 전기적신호를 인가받아 안착된 디스크의 반사면에 촛점을 집속시키는 광픽업 액츄에이터에 있어서, 상기 디스크의 반사면에 각기 다른 촛점을 집속시키는 제1대물렌즈(50) 및 제2대물렌즈(60)와, 상기 제1대물렌즈(50) 및 제2대물렌즈(60)가 각각 대향되어 설치되도록 해주는 제1렌즈공(41) 및 제2렌즈공(42)이 형성된 대물렌즈홀더(40)와, 상기 대물렌즈홀더(40)의 사각형 공간부내면에 부착되어 대물렌즈홀더(40)의 포커싱방향조정을 수행하는 포커싱조정코일(127)과, 상기 포커싱조정코일(127)의 일측면에 부착되어 대물렌즈홀더(40)의 트랙킹방향 조정을 수행하는 트랙킹조정코일(128)과, 상기 대물렌즈홀더(126)내에 설치된 포커싱조정코일(127) 및 트랙킹조정코일(128)이 유동가능하게 끼움 결합되는 내측요오크(121)와, 상기 대물렌즈홀더(40)내의 포커싱조정코일(127) 및 트랙킹조정코일(128)에 반발력을 발생시키는 영구자석(124)이 부착된 하나의 외측요오크(122)와 상기 내,외측 요오크(121)(122)가 설치되도록 해주는 플레이트(70)로 구성된 것을 특징으로 하는 와이어타입 광픽업 액츄에이터의 이중 대물렌즈 인바 0.6㎜와 1.2㎜ 두가지 디스크판을 모두 신속, 정확하게 재생하도록 해주는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foreign object lens of a wire type optical pickup actuator, wherein the optical pickup actuator focuses on a reflective surface of a mounted disk by receiving an electrical signal from a servo system. A first objective lens 41 for converging the first objective lens 50 and the second objective lens 60, and the first objective lens 50 and the second objective lens 60, respectively; An objective lens holder 40 having a second lens hole 42 and a focusing adjustment coil 127 attached to an inner surface of a rectangular space of the objective lens holder 40 to adjust the focusing direction of the objective lens holder 40. And a tracking adjustment coil 128 attached to one side of the focusing adjustment coil 127 to adjust the tracking direction of the objective lens holder 40, and a focusing adjustment coil 127 installed in the objective lens holder 126. ) And tracking adjustment coil (128) One inner yoke 121 which is fitted to be movable and a permanent magnet 124 for generating a repulsive force to the focusing adjustment coil 127 and the tracking adjustment coil 128 in the objective lens holder 40 are attached. Dual objective lens Invar 0.6 mm and 1.2 mm two discs of the wire type optical pickup actuator, characterized in that the outer yoke 122 and the plate 70 to allow the inner and outer yoke 121, 122 is installed It allows you to play all the plates quickly and accurately.
