ABSTRACT:
An optical information recording medium is provided that records and reproduces information by means of laser beams irradiated from the side of the light transmission layer. The optical information recording medium provides a large capacity and a high degree of reliability and is inexpensive. At least a reflective film and a light transmission layer are formed, in the presented order, on the information recording surface of the support substrate. Information is recorded and/or reproduced by using the laser beam irradiated from the side of the light transmission layer. The reflective film, which is made of an alloy containing Ni and Cr as main components, has a thickness of 20 nm or more to 80 nm or less.
