PURPOSE:To obtain an optical information recording medium high in recording sensitivity, by forming a reflection layer using a low melting metal or a dye having bronze gloss, and an absorption layer contg. a compd. having anthraquinone or indanthrene structure. CONSTITUTION:A reflection layer 2 contg. a low melting metal, such as Te, Bi, or alloy, or a dye having bronze gloss, such as cyanine or triphenylmethane type, is formed on a base 1, and a light absorption layer is formed on the layer 2 by vapor-depositing a compd. having anthraquinone or indanthrene structure or coating the layer 2 with a soln. contg. said compd. to obtain an optical information recordong medium. An undercoat layer 4 may be formed between the base 1 and the layer 2, and a protective layer 5, such as SiO2 layer, may be formed on the layer 3. The arrangement in which the layer 3 is formed on the base 1 and the layer 2 is formed on the layer 3 may be adopted. The recording medium thus obtained is capable of recoding semiconductor beams and being reproduced with said beams, and recording output beams lower than conventional ones. |
