Abstract

PURPOSE:To easily obtain a recording medium for recording and reproduction using a laser beam having a high reliability, free from deterioration in the quality and enabling high-sensitivity recording, by placing a monolayer information recording layer comprising a bronze-lustered organic pigment on a substrate. CONSTITUTION:A monolayer information recording layer 2 comprising a bronze- lustered organic pigment (e.g., copper phthalocyanine) is formed on a substrate 1 (pref. a plastic one made of an acrylic resin or the like) and preferably, a protective layer 3 (pref. a 0.5-2mum thin film made of polystyrene) is formed on said recording layer 2. To impart a bronze luster on the organic pigment layer, a thin film is formed on a heated substrate 1 by deposition such as vacuum vapor deposition of the organic pigment or other appropriate methods can be used. EFFECT:Improved contrast between the recorded part and the unrecorded part. Reproduction is possible both by reflection and transmission systems.
