Abstract:
An optical information recording medium that has a simple structure and with which warpage is kept to a minimum even under environmental changes over a wide range, and a method for manufacturing this medium are provided. The optical information recording medium is an optical information recording medium used for the reproduction of recorded information and for recording and reproduction, including a substrate having an information recording layer, and a light transmitting layer that covers the information recording layer and is composed of a radiation curable resin, wherein a warpage adjusting layer for adjusting warpage of the light transmitting layer caused by temperature changes is disposed on the opposite side of the substrate from the side on which the information recording layer is formed. There is included at least a temperature region that satisfies the relationship that the coefficient of linear expansion CL of the light transmitting layer
