Claims (1)
레이저광원으로부터 발사되는 레이저광을 집광하여서 디스크의 트랙에 투사되도록 하는 대물렌즈와, 상기 대물렌즈가 배설되고 전류가 도통되도록 T-코일 및 F-코일이 외주에 감겨진 브레이드부재와 상기 부레이드부재의 T-코일 및 F-코일에 자장이 형성되도록 자석 및 요크가 배설된 베이스 부재로 이루어져서 상기 부레이드,부재의 T-코일 및 F-코일에 전류가 도통될 경우 상기 브레이드부재가 구동되는 광학픽업 대물렌즈의 구동장치에 있어서, 상기 브레이드 부재의 대체로 중앙의 양측면에 각각 돌설된 돌설부와, 양단부에 고정부가 형성되고 양단부로부터 일정간격을 두고 중공부가 형성되어서 상기 돌설부에 일단의 고정부가 각각 고착되는 탄성수단과,상기 탄성수단에 형성된 중공부에 각가 삽입되는 댐퍼부재로 이루어져서, 댐퍼부재가 공진현상을 방지하여서 대물렌지가 레이저광을 디스크의 트럭에 편심됨이 없이 투사되도록 하는 것을 특징으로 하는 광학픽업 대물렌즈의 구동장치.An objective lens for condensing laser light emitted from a laser light source and projecting onto a track of a disc, a braid member and a braid member having a T-coil and an F-coil wound around the periphery so that the objective lens is excreted and current is conducted. An optical pickup in which the braid member is driven when a current is conducted to the T-coil and the F-coil of the blade, the member is formed of a base member having a magnet and a yoke to form a magnetic field in the T-coil and the F-coil of the member. In the driving device of the objective lens, a protrusion is formed on both sides of the center of the braid member, and a fixing part is formed at both ends, and a hollow part is formed at regular intervals from both ends so that one end of the fixing part is fixed to the protrusion. And a damper member having an angle inserted into a hollow portion formed in the elastic means, wherein the damper member is a resonance string. Hayeoseo prevent the objective lens of the optical pick-up it characterized in that the objective range to project the laser beam without being eccentric to the disk drive truck.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
