Abstract

본 발명은 광 픽업을 개시한다.The present invention discloses an optical pickup.

본 발명은 광 발생수단과, 이 광발생수단으로부터 조사된 광의 경로를 변경시키는 광 분할수단과, 이 광 분할수단에 의해 경로가 변경된 광을 접속하여 광 기록매체에 주사하는 접속수단을 구비하여 된 광 픽업에 있어서, 상기 광 분할수단이 제1광 분할면과 제2광 분할면이 V자의 형상으로 형성된 빔 스프리터를 구비하여 된 것에 그 특징이 있으며, 이는 그 구조가 간단하여 소형화가 가능한 이점을 가진다.The present invention includes light generating means, light splitting means for changing a path of light irradiated from the light generating means, and connecting means for connecting the light whose path has been changed by the light splitting means to scan the optical recording medium. In the optical pickup, the light splitting means includes a beam splitter having a first light splitting surface and a second light splitting surface having a V-shape, which is advantageous in that the structure can be reduced in size.
