Abstract:
1. An optical information recording medium comprising: a disk-like substrate having a hole in a central portion thereof; and a light-reflective layer, a dye recording layer comprising an organic dye, an intermediate layer comprising an inorganic substance, and a light-transmissive layer comprising a resin, disposed in that order on one principal surface of the substrate, in which information is recorded and/or reproduced by irradiation of laser light from the light-transmissive layer side, wherein the light-transmissive layer covers a surface of the intermediate layer from an inner peripheral edge of the intermediate layer to an outer peripheral edge of the intermediate layer, and a vicinity of an outer peripheral edge of the light-transmissive layer is in contact with the substrate over at least part of an annular region extending around an outer peripheral side of the substrate.
