Abstract
본 발명은 콤팩트 디스크 플레이어의 광 픽업장치에 관한 것으로서, 특히 두께가 1,2㎜인 기존의 오디오 디스크와 두께가 0.6㎜인 디지탈 비디오 디스크에 기록된 정보를 선택적으로 읽어들일 수 있도록 하는 콤팩트 디스크 플레이어의 광 픽업장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical pickup device for a compact disc player, and more particularly, to a compact disc player for selectively reading information recorded on existing audio discs having a thickness of 1,2 mm and digital video discs having a thickness of 0.6 mm. It relates to an optical pickup device.
이를 위하여 대물렌즈와 디스크 사이에 0.6㎜ 차의 두께를 보상하기 위한 보정부재를 배치하고, 현재 안치된 디스크의 두께를 센싱한 후 상기 감지된 디스크의 두께에 따라 콘트롤러에서 모터를 제어하여 상기 보정부재를 대물렌즈와 디스크 사이에 삽입 및 이격시키도록 함으로서 보정부재에 의해 0.6㎜의 두께 차를 보상하여 두께가 0.6㎜인 디지탈 비디오 디스크를 기존의 콤팩트 디지탈 오디오 디스크 플레이어의 광 픽업에서 읽어들일 경우 광학적인 수차를 감소시킴에 따라 노이즈가 최대한 억제되도록 함으로서 에러 발생율을 감소시켜 기록된 정보를 정확히 읽을 수 있도록 한 것이다.To this end, a compensation member is disposed between the objective lens and the disk to compensate for a thickness of 0.6 mm, the thickness of the currently placed disk is sensed, and then the controller is controlled by the controller according to the detected thickness of the disk. Is inserted and spaced between the objective lens and the disc to compensate for the 0.6 mm thickness difference by the correction member, so that when a digital video disc with a thickness of 0.6 mm is read from the optical pickup of a conventional compact digital audio disc player, By reducing the aberration, the noise is suppressed as much as possible, thereby reducing the error occurrence rate so that the recorded information can be read accurately.
