PURPOSE:To provide an optical information recording medium of high recording sensitivity, excellent reliability and low cost wherein a layer made of a specific material of which thermal conductivity is small is provided between a metal reflecting layer and a recording layer. CONSTITUTION:A metallic thin film 2 (e.g.: Al film of approximately 100- 5,000Angstrom in thickness) of high reflectivity of which condition is not changed by the thermal energy of a high density energy beam used (e.g.: He-Ne laser), a layer 3 of an organic compound having prophyrin nucleus (e.g.: layer of copper phthalocyanine of approximately 100Angstrom -5mu in thickness) and a thin film 4 (e.g: Te film of approximately 50-2,000Angstrom in thickness) of a metal (or a semimetal, chalcogenide compound) which changes its state in accordance with the thermal energy of a used high density energy beam are formed in sequence on a substrate 1 (e.g.: plastic plate) by using vacuum deposition method, spattering method, etc. to make an optical information recording medium. |
