Optical recording medium
Abstract:
A multilayer optical recording medium comprises four recording layers including an L0 layer, an L1 layer, an L2 layer, and L3 layer laminated between a substrate and an optically transparent cover layer and optically transparent spacer layers each provided between the recording layers. The L2 layer has the negative dependence of the reflectance on the incident angle of a laser light beam for reproduction. Crosstalk can be effectively reduced by the relation between the configuration of the respective recording layers and the crosstalk.
