An optical recording medium includes a plurality of information signal layers on which information signals are to be optically recorded. Among the plurality of information signal layers, the information signal layer closest to the light-receiving surface has a reflectance of more than 4%.
摘要:
In a case where (i) a reflectance calculated from a reflected light amount obtained from a longest pit (P1max) or a longest space (S1max) in a first pit row is defined as a first reflectance and (ii) a reflectance calculated from a reflected light amount obtained from a longest pit (P2max) or a longest space (S2max) in the second pit row is defined as a second reflectance, the first pit row is formed such that the first reflectance becomes substantially identical with the second reflectance.
摘要:
An optical device, such as an optical storage medium, comprises a layer of material in the solid state that has a refractive index that is switchable between at least two stable values by applied light. A reflector is spaced apart from the layer of material by a solid spacer layer transmissive to light.
摘要:
Provided is a recording film for an optical information recording medium with which it is possible to meet all predetermined characteristics requirements and increase productivity while reducing the number of layers in the optical information recording medium. The present invention relates to a recording film for an optical information recording medium on which recording is performed by laser light irradiation, wherein the recording film for an optical information recording medium includes: Mn; at least one element (group X element) selected from the group consisting of Bi, Ag, Co, Cu, In, Sn, and Zn (group X); and oxygen (O). At least some of the Mn and at least some of the group X element are oxidized.
摘要:
An information recording medium (100) of the present invention includes a substrate (1) and a recording layer provided on the substrate (1) and having optical properties that can be changed by irradiation with a laser beam. The recording layer is formed of a plurality of arrayed minute recording regions (e.g., phase-change particles (2)). A part or all of the recording region is made of a recording material containing Te and O. The recording region has a length of 30 nm or less in an information recording direction. Preferably, the recording material further contains an element M, where M is at least one element selected from the group consisting of Pd, Au, and Pt.

A silver-based magnesium alloy thin film is provided for the semi-reflective coating layer of optical discs. This alloy has moderate to high reflectivity and reasonable corrosion resistance in the ambient environment.
摘要:
There is provided an optical recording medium including a substrate, an information recording layer that is formed on the substrate and has a single film structure formed by an oxide including W and Ru, and a light transmissive layer that is formed on the information recording layer.
摘要:
An optical recording medium including a substrate and two or more recording layers that contain Pd, O, and M (M comprises at least one of Zn, Al, In, and Sn), where O is contained in an amount greater than a stoichiometric composition thereof when M is completely oxidized (into ZnO, Al2O3, In2O3, and SnO2). An nth recording layer of the two or more recording layers, as counted from an opposite side of an incident side of recording light, has a Pd content that is less than that of an (n−1)th recording layer.
