Abstract

본 발명은 광학적 수법에 의해서 정보신호의 판독을 행하기 위해서 반사층을 내포하는 광학적 정보 기록 매체에 관한다. 이 광학적 정보 기록 매체는, 플라스틱 기판으로 이루어진다. 이 발명에서는, 그 광학적 정보 기록 매체의 기록 내용이, 예를 들면 게임프로그램인가 음악정보인가등, 어떠한 종류의 정보인가를 인간의 시각에 의해서 순간에 판단할 수 있도록 기판에 염료를 혼입시켜 착색한다. 통상 염료등의 불순물을 혼입시키면 판독장치의 광학계에 영향을 주어, 판독이 곤란하게 되지만, 염료의 입자직경을 50㎛이하로 하는 것으로, 광학계에의 영향을 배제할 수 있다.
