Abstract
본 발명은 광디스크 및 그 제조방법에 관한 것으로서, 제조가 용이하고. 반사효율이 대폭 향상된 광디스크 및 그 제조방법을 제공한다. 본 발명은, 상면에 피트가 형성된 수지층과, 상기 수지층의 피트 위에 접착되며 한가지 파장만을 전반사시키는 반사홀로그램 필름과, 상기 반사홀로그램 필름위에 형성되는 보호층을 구비하여 구성된다. 따라서 제조가 용이하고, 반사효율이 거의 100%에 가까워 저출력 반도테 레이저의 채용이 가능하게 되는 이점을 가진다.The present invention relates to an optical disc and a method of manufacturing the same, and is easy to manufacture. Provided are an optical disk and a method of manufacturing the same, which have greatly improved reflection efficiency. The present invention comprises a resin layer having a pit formed on an upper surface thereof, a reflective hologram film adhered to the pit of the resin layer and totally reflecting only one wavelength, and a protective layer formed on the reflective hologram film. Therefore, it is easy to manufacture, and the reflection efficiency is almost 100%, which has the advantage that it is possible to employ a low-power bandote laser.
