Optical information recording medium and manufacturing method therefor
摘要:
A multilayer type optical information recording medium in which in multilayering of a write-once type optical information recording medium, when a second film is formed using a metallic stamper, a protective layer composed of an inorganic material is free from peeling, is provided. In the multilayer type optical information recording medium including an interlayer, the interlayer is constituted by multiple films of a first film contacting a protective layer and a second film contacting a reflection layer; materials of the first and second films are constituted of materials different from each other; and a peeling resistance of the material of the first film against a material of the protective layer of the first optical information recording layer is higher than that of the second film.
