Claims (1)

레이저광원으로부터 발사되는 레이저광을 집광하여서 디스크의 트랙에 투사시키는 대물렌즈와, 상기 대물렌즈가 배설되고 외주에 전류가 도통되는 F-코일 및 T-코일이 감겨진 브레이드 부재와, 자장이 형성되는 베이스부재로 구성된 광학 픽업 대물렌즈의 구동장치에 있어서, 상기 브레이드 부재의 양측면 모서리에각각 고착된 8개의 제1자석 부재와, 상기 베이스부지에 “+ ”자 형상으로 돌설된 2개의 제2자석 부재로 이루어져서 상기 브레이드 부재가 제1자석부재 및 제2자석 부재로부터 발생되는 자력에 의해서 원활하게 구동되도록 지지되는 것을 특징으로 하는 광학 픽업 대물렌즈의 구동장치.An objective lens for condensing the laser light emitted from the laser light source and projecting it onto a track of the disc, an F-coil and a T-coil wound braid member in which the objective lens is disposed and the current is conducted to the outer periphery, and a magnetic field is formed. An apparatus for driving an optical pickup objective lens composed of a base member, comprising: eight first magnet members fixed to both side edges of the braid member and two second magnet members protruding in a “+” shape on the base site; And the braid member is supported to be smoothly driven by the magnetic force generated from the first magnetic member and the second magnetic member. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
