1 Abstract

An optical recording medium has a recording layer formed on a substrate possessing a light transmissive property, through which a light for recording and reproducing is irradiated to the recording layer. The substrate contains a light absorbent so as to allow only the light for recording and reproducing to pass through the substrate. The recording medium exhibits a good light-resistance.
