Abstract:
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.
