Patent ID: 7675838

Claim:
An optical recording medium comprising: a substrate; an optically transparent cover layer; at least three recording layers including an L0 layer, an L1 layer, and an L2 layer provided between the substrate and the optically transparent cover layer, the recording layers laminated in this order from the substrates side; optically transparent spacer layers each provided between the recording layers; and at least one recording layer from among the recording layers except the L0 layer has a negative dependence of the reflectance on an incident angle of a laser light beam for reproduction, wherein the recording layer having the negative dependence of the reflectance on the incident angle has a relative reflectance Rth of 0.9 or less at a beam spot diameter position of the recording layer, the relative reflectance being defined as a ratio of the reflectance at the incident angle θ of a laser light for reproduction to the reflectance at an incident angle of 0°.
