Abstract

본 발명은 기판위에 팽창층과 소거층이 형성된 광학기록매체로서, 팽창층(2)과 소거층(3) 사이에 일반식(1)로 표시되는 금속적인 반사를 나타내는 유기색소 단결정의 단독 반사층(4)을 두거나, 소거층을 일반식(1)의 유기색소 단결정과 기타 유기색소와의 혼합소거층(3´)으로 구성하여 기록의 재생시 기록부와 미기록부의 반사율 차이의 증가로 콘트라스트가 향상되고 C/N비가 증가하는 효과가 있으며, 기록의 소거시에는 열패드에 의한 접촉방식이나 열조사에 의한 열전달로 기록을 소거시키는 소거 가능한 광학 기록매체에 관한 것이다.The present invention provides an optical recording medium having an expansion layer and an erasing layer formed on a substrate, wherein a single reflection layer of an organic dye single crystal exhibiting metallic reflection represented by the general formula (1) between the expansion layer 2 and the erasing layer 3 ( 4) or the erasing layer is composed of a mixed erasing layer (3 ') of the organic dye single crystal of the general formula (1) and other organic dyes, and the contrast is increased by increasing the reflectance difference between the recording part and the unrecorded part during reproduction of recording The present invention relates to an erasable optical recording medium for erasing a recording by heat transfer by a contact method or heat irradiation by a thermal pad.
