ABSTRACT:
An optical recording medium is provided which includes two or more information layers in which an Sb-based eutectic material is used as the material for a recording film of a translucent information layer. There is also provided a recording film material for the optical recording medium. The translucent information layer is configured to include a recording film formed of a phase change material SbxGeyInzcontaining Sb, Ge, and In in an atomic ratio of x:y:z, where 5≦y≦15 and 4≦z≦15 are satisfied. The recording film further includes Te in an atomic ratio of a, provided that x+y+z+a=100 and 4≦a≦15 are satisfied. An interface layer formed of a ZrO2—Cr2O3film having a thickness of 2 nm or more and 10 nm or less is provided on the laser beam incident side of the recording film. When the compositional ratio of the ZrO2—Cr2O3film is given by ZrO2:Cr2O3=B:C (mol %), 20≦B≦90, 10≦C≦80, and B+C=100 are satisfied.
