ABSTRACT:
An optical information recording medium includes a disc-shaped substrate, at least one information recording layer formed over a recording/reproducing-side main surface of the substrate, a light transmitting layer formed over the information recording layer, and a protecting layer formed to cover the light transmitting layer and at least one part of a side end surface perpendicular to the main surface of the substrate. At least the part of the side end surface is covered with the protecting layer for covering the recording/reproducing-side main surface, and the surface of the protecting layer covering at least the part of the side end surface has a larger surface roughness than that of the surface of the protecting layer covering the upper of the recording/reproducing-side main surface.
