    摘要: According to one embodiment, an information storage medium has a substrate, a first recording layer containing an organic dye material, a first barrier layer, a spacer layer, a second recording layer, a second barrier layer, and a protective layer formed on the second barrier layer. The angle that the outer side surface and inner side surface of the protective layer make with a direction parallel to the surface of the second barrier layer is 30° to 150°, at least one of the first and second barrier layers has lands and grooves on its two major surfaces and the depth of the lands on one major surface is smaller than that of the lands on the other major surface close to the substrate, or the first and second barrier layers are made of a material formable by coating.

    摘要: According to one embodiment, single-sided dual-layer recordable disc 100 may be used. Information recording is performed by forming mark and space portions on data area DA using modulated laser power. Pp denotes the maximum laser power or peak power for forming the mark portion, and Pb denotes the bias power for forming the space portion. Power ratio Pb/Pp is calculated for each of recording layers L0 and L1. Information is recorded on any of the recording layers L0 and L1 based on the result of calculation. Here, the calculated power ratio Pb/Pp changes among the recording layers L0 and L1, thereby optimizing the recording condition for a multi-layer recordable optical disc within relatively short time.
