摘要：
According to one embodiment, in a phase-change optical disk which has a substrate and a stacked structure including an interference film, a phase-change recording film, an interface film, and a reflecting film and which enables the recording film to be recorded into or erased from reversibly with light, the elements constituting the recording film have a segregation or a concentration distribution in the direction of the thickness of the recording film from a region in contact with the phase-change recording film, or in the in-plane direction (or in the direction perpendicular to the thickness) of the recording film.
