Abstract

본 발명은 광픽업용 대물렌즈 구동장치에 관한 것이다.The present invention relates to an objective lens driving apparatus for optical pickup.

본 발명은 광디스크 플레이어 등에 설치되어 사용되는 것으로서, 소정 형태의 보빈과, 상기 보빈에 설치되며 대물렌즈를 수직 이동시키기 위한 자장을 형성하는 포커싱 코일과, 상기 보빈에 설치되며 대물렌즈를 수평 이동시키기 위한 자장을 형성하는 트랙킹 코일을 구비하는 광픽업용 대물렌즈 구동장치에 있어서, 상기 포커싱 코일과 트랙킹 코일은 상기 보빈에 상호 교차되어 권선되어 있는 것을 특징으로 한다.The present invention is installed and used in an optical disk player, a bobbin of a predetermined form, a focusing coil installed on the bobbin to form a magnetic field for vertically moving the objective lens, and installed on the bobbin for horizontally moving the objective lens. An objective lens driving apparatus for an optical pickup having a tracking coil for forming a magnetic field, wherein the focusing coil and the tracking coil are wound on the bobbin to cross each other.
