ABSTRACT:
An optical information recording medium includes a substrate having a thickness of approximately 1.0 mm to 1.2 mm, with a spiral pre-groove being formed at a predetermined area on the substrate excluding a central hole and an outer periphery. Successively disposed on the area at which the pre-groove is formed are a light-reflective layer, a recording layer that can record information when irradiated with light having a wavelength range of 380 nm to 500 nm, a protective layer for protecting the recording layer, an adhesive layer made of a photocurable resin that has been cured by being irradiated with visible light, and a thin transparent protective layer.
