摘要： The optical recording medium has sandwiched between protective layers a mask layer whose refractive index is changed in one part within a light spot when irradiated with a laser beam of 2 to 4 mW. In a region where the refractive index is changed or in other remaining regions, the difference in the amount of reflected light between the crystalline state and the amorphous state is so small that a reproduced signal is difficult to identify. By reducing the size of a portion where the reproduced signal can be seen, it is possible to read high-density recorded information.

摘要： A recording medium having a dummy signal area on at least one side of a recording area is used and information is recorded with a dummy signal added to at least one of the leading and trailing sides in the recorded information signal. The user data area remains unaffected by repeated overwriting so that recorded user data is reproduced correctly. In particular, the wave form distortion caused by fluidization of a recording film remains at the dummy signal area and does not affect the user data area, so that the reproduction of the target information (user data) is assured.

摘要： This invention relates to an information-recording medium that is used for recording information through radiation of energy beam. The information recording medium has a groove-shaped information recording track and is provided with a recording layer, one or more kinds of heat sink control layers and heat sink layers. A sum of film thickness of the more than one kind of recording layer is equal to or less than a step between information recording tracks, and a sum of film thickness of one or more kinds of heat sink control layers is more than a groove depth of the information recording track. With this configuration, no cross-erase is produced even if the information-recording medium is applied for a high density recording with the track pitch being 70% or less.

摘要： An information storage medium includes a substrate, a thin film formed on the substrate and having a reflectance changed by a phase change caused by irradiation of an energy beam irradiated via the substrate and a first reflective layer and a second reflective layer on the film directly or via an intermediate layer. The thin film includes one of In3SbTe2, In35Sb32Te33, In31Sb26Te43 and Ag—In—Sb—Te. The first reflective layer and the second reflective layer are piled up in the recited order from a thin film side with the first reflective layer consisting of a material having an attenuation factor k of 2 or less and selected from a group of silicon based materials and the second reflective layer consisting of a material having an attenuation factor k of at least 3.
