摘要：
An optical information recording medium is provided with a substrate having a pregroove formed on one main plane; a reflecting layer arranged on the one main plane of the substrate and reflecting an access controlling laser beam; a selective reflecting layer arranged on the reflecting layer, transmitting the access controlling laser beam and reflecting a recording laser beam; a recording layer arranged on the selective reflecting layer for having information recorded thereon by the recording laser beam; and a reflection preventing layer arranged on the recoding layer. On the substrate, a dummy groove having a shape similar to that of the pregroove is formed on forming regions adjacent to an effective access region on the one main plane.
