Abstract

본 발명은 발광수단에서의 수평방향의 비임을 하방으로 굴절시키는 굴정장치를 광경로상에 구성함으로써 더욱 박형으로 구현할 수 있는 박형 광픽업장치에 관한것이다.The present invention relates to a thin optical pickup device that can be realized even thinner by configuring a refraction device that refracts the beam in the horizontal direction downward in the light emitting means on the optical path.

본 발명에 의한 박형 광픽업장치는 수평방향의 비임을 발사하기 위한 발광수단 발광수단에서의 비임을 하방으로 굴절시키기 위한 굴절수단, 상기 굴절수단에서의 비임을 상방으로 반사하기 위한 미러, 반사된 비임을 디스크의 기록면에 집광시키기위한 집광수단; 그리고 디스크의 기록면에서 반사된 비임을 상기 광경로를 거쳐 수광하기 위한 수광수단을 포함하여 구성된다.The thin-film optical pickup apparatus according to the present invention includes a refraction means for refracting a beam downward from a light emitting means for emitting a beam in a horizontal direction, a mirror for reflecting a beam from the refraction means upward, a reflected beam Condensing means for condensing the light on the recording surface of the disk; And light receiving means for receiving the beam reflected from the recording surface of the disk via the optical path.
