Abstract
본 발명은 양면디스크 광픽업장치에 관한 것으로, 종래의 장치중 2개의 픽업을 사용하는 경우는 픽업의 가격이 비싸기 때문에 비용이 많이드는 문제점이 있었고, 1개의 픽업을 U자형으로 이동시키는 경우는 U자형 랙크의 설치에 따른 복잡한 기구물이 필요하기 때문에 구성이 복잡해 지는 문제점이 있었다. 본 발명은 이러한 종래의 문제점을 해결하기 위해 신호의 기록/재생을 위한 광빔을 발사하는 광원과; 상기 광원으로부터 발사된 광빔을 소정의 방향으로 분리하는 광분리수단과; 상기 분리된 광빔을 디스크로 입사시켜주는 반사수단과; 상기 반사수단에 의해 디스크에 입사된 빛이 반사되면 이를 검출하는 광검출수단으로 구성한 양면디스크 광픽업장치를 창안한 것으로, 이와같이 광빔을 분리하는 홀로그램광학소자와 이를 반사하는 미러로 구성된 한 개의 광픽업만을 이용하여 디스크의 양면의 기록/재생을 할수 있어 비용이 절감되고 구조가 간단해지는 효과가 있다.The present invention relates to a double-sided disk optical pickup device, and when using two pickups of the conventional apparatus, there is a problem that it is expensive because the price of the pickup is expensive, and in the case of moving one pickup to U shape There is a problem in that the configuration becomes complicated because a complicated mechanism is required according to the installation of the male rack. The present invention provides a light source for emitting a light beam for recording / reproducing a signal in order to solve this conventional problem; Optical separation means for separating the light beam emitted from the light source in a predetermined direction; Reflecting means for injecting the separated light beam into a disk; Invented a double-sided disk optical pickup device comprising a light detecting means for detecting the light incident on the disk by the reflecting means, the optical pickup device comprising a holographic optical element for separating the light beam and a mirror reflecting the light beam Only by using both sides of the disk can be recorded / reproduced, the cost is reduced and the structure is simple.
