摘要:
Provided is an optical recording medium including, in sequence: a first substrate; a first information recording layer; an intermediate layer; a second information recording layer; and a second substrate having wobble convex portions on its surface, wherein information is recorded on or reproduced from the first information recording layer and second information recording layer by irradiation with a laser beam from a first information recording layer side, wherein the second information recording layer includes, over the second substrate, a light reflective layer, a dye recording layer, and an inorganic protective layer, wherein the inorganic protective layer has a thickness of 3 nm to 40 nm, and wherein the dye recording layer includes a cyanine compound expressed by General Formula (I) and a squarylium compound expressed by General Formula (II):
