ABSTRACT:
An information recording medium includes a substrate and a recording portion having recording layers on the substrate, wherein the recording portion is capable of three-dimensional recording by changing an optical constant of the recording layers by irradiation of recording light, and a first reflected-light reducing portion for reducing reflected lights of reproducing light from the substrate side is provided at a side opposite to an incident side of the reproducing light with respect to the recording portion, and an optical information recording/reproducing apparatus records and reproduces information to and from the medium.
