Abstract

본 발명은 LDP/CDP 및 광디스크 드라이버의 대물렌즈 촛점을 정확히 맞추기 위한 대물렌즈 구동장치에 관한 것으로, 사각기둥 형태의 중간가동부(11)(12)와, 중심에 광경로홀이 뚫려있고 상부에 대물렌즈(19)가 결합되는 사각기둥 형태의 대물렌즈홀더(14)와, 상기 대물렌즈 홀더의 4측면중 2측면에 부착된 포커싱용 판스프링(13) 및 나머지 2측면에 부착된 영구자석(15)(16)과, 상기 중간가동부와 고정부(30) 사이에 설치된 트랙킹용 판스프링(20)(21)과, 상기 영구자석과 대향하여 근접하게 설치된 포커스를 코일(17)과 트랙킹용 코일(18)를 구비하여 상기 중간가동부와 대물렌즈홀더가 고주파수에 의하여 공진되지 않도록 한것이다.The present invention relates to an objective lens driving device for precisely focusing an objective lens of an LDP / CDP and an optical disk driver. The objective lens holder 14 having a square pillar shape to which the lens 19 is coupled, the focusing plate spring 13 attached to two sides of the four sides of the objective lens holder, and the permanent magnet 15 attached to the remaining two sides. 16, the tracking plate springs 20 and 21 provided between the intermediate movable part and the fixed part 30, and the focusing coils 17 and tracking coils provided in close proximity to the permanent magnets. 18) to prevent the intermediate moving part and the objective lens holder from resonating by high frequency.
