摘要： 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.

摘要： A holographic recording medium 10 is configured to have a recording layer 12 on which information can be recorded as holograms; and first and second heat generating layers 14A and 14B provided in a pair so as to sandwich the recording layer 12. Then, the first and second heat generating layers 14A and 14B are allowed to generate heat by being irradiated with a heat generating laser beam LB3 having a wavelength that is different from that of a signal beam LB1 or a reference beam LB2 for reproducing or recording information. The holographic recording medium and a method for recording and reproducing the same, and a recording and reproducing apparatus can compensate for shrinkage of the recording layer due to recording or variations in temperature, thereby allowing for reproduction of the holograms under optimum conditions.

From among the plurality of information layers, the information layer excluding the information layer arranged closest to the substrate and the information layer adjacent to the information layer closest to the substrate has asymmetrical reflection characteristics in which reflectance on the substrate side when light incident from the substrate side is reflected on the information layer toward the substrate side is lower than the reflectance on the cover layer side when light incident from the cover layer side is reflected on the information layer toward the cover layer side.
