Abstract

광디스크등의 광학기록매체의 신호기록면상에 광원으로부터의 빛을 집광시키기 위한 광학픽업장치이다. 광학픽업장치의 반구형렌즈(9)는 광디스크(20)를 대향하는 평면(9a)을 가지며 소정의 굴절율을 갖는다. 광학픽업장치는 또한 렌즈(9)를 고정하고 광디스크(20)와 슬라이딩 접촉되도록 사용된 슬라이더(12)와, 광디스크(20)와 슬라이딩 접촉하여 슬라이더를 가압하여 지지하기 위해 사용된 스프링판(13)과를 지니고 있다. 광학픽업장치에 따르면, 고밀도의 재생이 실현될 수 있는 한편, 디스크성형시 뒤틀림에 대한 허용치 또는 흡습으로 인한 뒤틀림에 대한 허용치가 작아질 수 있다. 게다가, 제품생산성 및 디스크재료를 선택하는 자유도도 또한 증진될 수 있다.
