Abstract

광기록매체의 정보를 기록재생하는 광픽업이 개시되어 있다. 개시된 광픽업은 2장 이상의 광기록매체에 공용하기 위하여 광빔의 영향을 전환할 수 있도록 배려된 것이다. 이를 위하여 레이저 다이오드로부터 방사되는 광빔의 경로상에 회전가능한 반사경을 구비하고 그 반사경의 반사경로상에 각 광기록매체에 광빔을 접속하는 대물렌즈 등을 부가한다. 그 반사경은 선택된 광기록매체를 향해 회전조작되어 그 선택된 광기록매체로 광빔을 반사시킨다. 레이저 다이오드와 반사경 사이에는 반사빔을 분리시키는 하프미러를 배치하여 그 하프미러에서 반사되는 반사빔을 광검출기로 수광한다. 개시된 광픽업은 2장 이상의 광기록매체에 공용되므로 트윈 디스크 플레이어 등의 원가절감에 기여한다. <제3도>An optical pickup for recording and reproducing information of an optical recording medium is disclosed. The disclosed optical pickup is considered to be able to switch the influence of the light beam in order to share the two or more optical recording media. To this end, a rotatable reflector is provided on the path of the light beam emitted from the laser diode, and an objective lens or the like for attaching the light beam to each optical recording medium is added on the reflection path of the reflector. The reflector is rotated toward the selected optical recording medium to reflect the light beam onto the selected optical recording medium. A half mirror for separating the reflected beam is disposed between the laser diode and the reflector, and the reflected beam reflected by the half mirror is received by the photodetector. Since the disclosed optical pickup is common to two or more optical recording media, it contributes to cost reduction of a twin disc player or the like. <Figure 3>
