Abstract
본 발명은 일게트로크로믹 시스템을 이용한 컴팩트 디스크 픽업장치에 관한 것으로, 전도성 인듐규소산화물(ITO)가 각각 피복되어 있는 제1기판 및 제2기판과, 상기 제1기판의 피복층위에 산화물이 층착되어 있는 반응 전극과, 상기 제2기판의 피복층위에 산화물이 증착되어 있는 카운터 전극과, 그리고 상기 반응 전극과 카운터 전극의 사이에 형성되어 있는 전해질로 구성되어 있는 일렉트로크로믹 시스템을 이용하여 레이저 빔의 크기를 가역적으로 조절함으로써, 단일의 레이저광을 이용하여 상이한 밀도로 저장된 CD의 정보를 판독할 수 있는 CD픽업장치가 제공된다.The present invention relates to a compact disc pick-up apparatus using a monogetrochromic system, wherein an oxide is deposited on a first substrate and a second substrate coated with a conductive indium silicon oxide (ITO), and a coating layer of the first substrate. Size of the laser beam using an electrochromic system consisting of a reactive electrode, a counter electrode on which an oxide is deposited on the coating layer of the second substrate, and an electrolyte formed between the reactive electrode and the counter electrode. By reversibly adjusting, a CD pickup apparatus capable of reading information of a CD stored at different densities using a single laser light is provided.
이와 같은 본 발명에 따르면 레이저빔의 색수차에 큰 영향을 미치는 편광필터등이 사용되지 않으며, 또한 전체시스템을 고상으로 형성할 수 있으므로 크기가 작은 CD픽업 장치의 제조가 가능하다. 또한, 착새과 탈색에 대한 기억능력이 있으므로 에너지는 착색 및 탈색시 제한적으로 소모되는 것에 불과하여 최소화할 수 있는 잇점도 있다.According to the present invention, a polarization filter or the like having a great influence on chromatic aberration of the laser beam is not used, and the whole system can be formed in a solid state, so that a compact CD pickup device can be manufactured. In addition, since there is a memory capacity for the coloration and discoloration, the energy is limited to consume only at the time of coloring and discoloration, there is an advantage that can be minimized.
