An optical information recording medium, which includes both of a land surface and a groove surface as a recording track and presents high signal quality. The optical information recording medium includes both a land and a groove as the recording track on a substrate, in which a laser light is irradiated from a reverse side of the substrate to thereby carry out a recording and a reproduction, and an inclination angle of a groove side is 25 or more and 40 or less, and both of arithmetic average roughness (Ra) on the land surface and the groove surface are assumed to be 0.2 to 0.7 nm.
