Abstract

본 발명은 광 디스크 및 제조방법을 개시한다.The present invention discloses an optical disc and a manufacturing method.

종래 광 디스크는 일면 광 디스크 또는 양면 광 디스크가 제안되어 있다. 이와같은 광 디스크에 있어서 특히 양면 광 디스크는 일면 광 디스크에 비하여 고밀도의 기록/재생이 가능한 이점이 있으나 이를 재생하기 위한 광 디스크 기록/재생장치의 구조가 복잡하고 도한 그 제조가 어렵다는 문제점이 있다. 이를 위하여 본 발명은 주사되는 서로 다른 파장을 선택적으로 반사시키는 유전체 코팅층을 경계로 하여 한 몸체안에 복수개의 기록층을 형성함으로써 고밀도의 기록/재생 및 단가절감을 도모하였다.Conventional optical disks have been proposed as single-sided optical disks or double-sided optical disks. In such an optical disk, in particular, a double-sided optical disk has an advantage that high-density recording / reproducing is possible as compared with a single optical disk, but the structure of the optical disk recording / reproducing apparatus for reproducing the optical disk is complicated and difficult to manufacture. To this end, the present invention achieves high-density recording / reproducing and cost reduction by forming a plurality of recording layers in one body with a dielectric coating layer that selectively reflects different wavelengths to be scanned.
