摘要: The information recording medium of the present invention comprises at least one of the following oxide-based material layers: (I) an oxide-based material layer containing Zr, at least one element selected from the group GL1 consisting of La, Ga and In, and oxygen (O); (II) an oxide-based material layer containing M1 (where M1 is a mixture of Zr and Hf, or Ht), at least one element selected from the group GL2 consisting of La, Ce, Al, Ga, In, Mg and Y, and O; (III) an oxide-based material layer containing at least one element selected from the group GM2 consisting of Zr and Hf, at least one element selected from the group GL2, Si, and O; and (IV) an oxide-based material layer containing at least one element selected from the group GM2, at least one element selected from the group GL2, Cr, and O. This oxide-based material layer can be used, for example, as a dielectric layer.
