ABSTRACT:
An optical recording medium includes a substrate, a light transmission layer and a plurality of recording layers between the substrate and the light transmission layer and capable of recording data in the plurality of recording layers and reproducing data recorded in the plurality of recording layers by projecting a laser beam via the light transmission layer onto the plurality of recording layers, at least one recording layer other than a farthest recording layer from the light transmission layer including a reflective film containing Ag as a primary component and C as an additive. In the thus constituted optical recording medium, recording characteristics and reproducing characteristic of the respective recording layers can be improved.
