    摘要: A phase change optical recording medium in which writing, reading and/or erasing of information is conducted by utilizing change of phase of a recording layer by irradiation of a light beam, said recording medium comprising a substrate, a first transparent protecting layer of an amorphous dielectric material on the substrate, a recording layer of a chalcogen alloy on the first transparent protecting layer, an adhesive layer of a crystalline sulfide 10 to 30 nm thick on the second recording layer, a second transparent protecting layer of an amorphous dielectric material on the adhesive layer, and a reflection layer of a crystalline alloy mainly comprising aluminum on the adhesive layer.
