Abstract
본 발명은 액정을 이용한 고밀도 광 디스크에 관한 것으로, 2층으로 데이터를 기록한 데이터 기록층과, 이 데이터 기록층 사이에 형성된 투명전극과, 이 투명전극 사이에 액정을 주입하여 형성된 액정층을 구비하여 이루어져, 상기 투명전극에 인가되는 전압에 따라 투과율이 변화되는 액정층을 이용하여 광 픽업에서 조사되는 레이저 빔을 투과 또는 반사시킴으로써 광 디스크에 2층으로 기록되어 있는 데이터를 선택적으로 읽어들일 수 있게 하여 광 디스크에 기록할 수 있는 데이터의 양을 두배로 늘인다.The present invention relates to a high-density optical disk using liquid crystal, comprising a data recording layer for recording data in two layers, a transparent electrode formed between the data recording layer, and a liquid crystal layer formed by injecting liquid crystal between the transparent electrodes. By transmitting or reflecting the laser beam irradiated from the optical pickup by using a liquid crystal layer whose transmittance changes according to the voltage applied to the transparent electrode, it is possible to selectively read the data recorded in two layers on the optical disk Double the amount of data that can be written to the optical disc.
