    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 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.
