Abstract

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

본 발명은, 그 내면에 빔 발생부와 수광부가 마련되며, P편광 또는 S편광중 어느 한 편광을 발생시키는 편광 레이저; 상기 편광 레이저의 광 경로상에 위치되며, 편광 레이저로 부터 주사된 편광을 전반시키고, 다른 파장을 갖는 편광은 전투과 시키는 편광 프리즘; 상기 광 디스크와 대향되는 편광 프리즘의 일측면에 마련되어 주사되어진 편광을 다른 편광으로 변환 반사시키는 변환판; 상기 편광 프리즘과 광 디스크 사이에 위치되며 편광 레이저로 부터 주사되어진 편광을 광 디스크에 집속시키는 집속수단을 포함하여 된 것으로서, P. S편광중 어느 한 편광을 발생시키는 편광 레이저왕 변환판 그리고 편광 프리즘을 통해 광 디스크에 기록/재생을 용이하게 행할 수 있으며, 특히 광 손실이 거의 발생되지 않음으로써 광효율의 향상을 동시에 꾀할 수 있는 이점이 있다.The present invention provides a beam generating unit and a light receiving unit on the inner surface thereof, the polarizing laser for generating any polarized light of P polarization or S polarization; A polarizing prism, positioned on the optical path of the polarizing laser, for propagating the polarized light scanned from the polarizing laser, and having polarized light having a different wavelength; A conversion plate provided on one side of the polarizing prism opposite to the optical disk to convert and reflect the scanned polarized light into another polarized light; And a focusing means positioned between the polarizing prism and the optical disk and focusing the polarized light scanned from the polarizing laser onto the optical disk, wherein the polarizing laser king conversion plate and polarizing prism generating any polarization of P. S polarization Through this, recording / reproducing on the optical disk can be easily performed, and in particular, since optical loss is hardly generated, there is an advantage that the optical efficiency can be improved at the same time.
