Abstract:
1. An optical recording medium comprising: a transparent substrate; a recording layer having the main component of organic dyes; an optical reflective layer; and a protective layer, wherein the recording layer, the optical reflective layer, and the protective layer are formed on the substrate in this sequence, recording at a recording linear velocity of 27.9 m/s or more is possible, wherein the optical reflective layer comprises any one of Ag and an alloy mainly made from Ag and a x-ray diffraction spectrum of the optical reflective layer satisfies the following relational expression: wherein I (111) is an intensity of the x-ray diffraction peak from (111) plane and I (200) is an intensity of the x-ray diffraction peak from (200) plane determined by x-ray diffraction based on 0-20 method when the incidence angle relative to the surface of the optically transparent substrate being θ.
