Patent ID: 8437243

Claim:
An optical information recording medium comprising, on a substrate: a plurality of information recording layers from which information can be read out by reproduction light; an intermediate layer separating each of the plurality of information recording layers; and a light transmitting layer provided in a position farthest from the substrate, the plurality of information recording layers including a layer allowing only readout of information and a rewritable layer including an area where information is rewritable, the rewritable layer including an area where information is rewritable, being an information recording layer provided in a position farthest from the light transmitting layer and also being a recording layer of disc type identification information and an individual identification number recorded in a format allowing easier detection as compared to an information recording format used for the layer allowing only readout of information by use of light irradiation, the layer allowing only readout of information, having pre-pits formed in a recording format in which a polarity of a push-pull signal obtained when provided information is reproduced is positive, and the light transmitting layer having a surface configuration and/or material selected so as to be one with antifouling property and mar-proof property set based on the rewritable layer.
