ABSTRACT:
An optical information recording medium has tolerance to warping. The optical information recording medium includes at least one information recording layer on a main surface of a substrate and a light-transmitting layer. The substrate includes a clamp area and an information recording area in accordance with the information recording layer. In the light-transmitting layer, the average thickness of a second area corresponding to the clamp area is thinner than the average thickness of a first area corresponding to the information recording area.
