Abstract
본 발명은 광학 데이타기록 매체에 신호를 기록하고, 그 기록된 정보를 전기신호를 재생시키는 광 픽-업장치에 관한 것으로서, 특히 홀로그램소자의 홀로그램 광학소자에 반사미러를 일체로 형성함으로서 조립 및 조정의 용이성과 경박단소화에 기여할 수 있도록 하는 일체형 광 픽-업장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical pick-up apparatus for recording a signal on an optical data recording medium and reproducing the recorded information with the recorded information. Particularly, assembling and adjusting by integrally forming a reflection mirror in the holographic optical element of the hologram element An integrated optical pick-up apparatus for contributing to the ease and light weight of the device.
이를 위하여 레이저 다이오드, 광검출기 및 회절격자와 홀로그램격자로 구성된 홀로그램 광학소자가 일체로 형성된 홀로그램소자를 구비하고, 대물렌즈에 의해 빔을 집광하여 광 디스크의 정보를 읽어들이는 홀로그램소자를 이용한 광 픽-업장치에 있어서, 상기 홀로그램 광학소자에 형성된 홀로그램격자의 일측에 임의의 경사면을 갖는 반사미러를 일체로 형성하여 상기 홀로그램소자에서 레이저빔을 상기 대물렌즈로 직접 조사토록 한 것이다.To this end, it comprises a hologram element formed integrally with a laser diode, a photodetector and a hologram optical element composed of a diffraction grating and a hologram lattice, and an optical pick using a hologram element that condenses a beam by an objective lens and reads information of an optical disc. In the up-up device, a reflection mirror having an arbitrary inclined surface is integrally formed on one side of the hologram grating formed in the holographic optical element so that the laser beam is directly irradiated from the hologram element to the objective lens.
