ABSTRACT:
When information is recorded on and/or reproduced from an optical recording medium by irradiating rays of light on its information recording layer having a reflective film from the side where the reflective film is deposited, the noise can be reduced. The optical recording medium includes a substrate having a minute uneven portion formed on its surface, a reflective film formed by ion beam sputtering on the minute uneven portion of the substrate, and a transparent film as a light transmission layer deposited and formed on the reflective layer.
