ABSTRACT:
In an information recording medium of the present invention, a recording layer and first and second dielectric layers are formed on a surface of a substrate. In the recording layer, at least one of recording and reproduction is caused by irradiation of light or application of electric energy. The dielectric layers are oxide-based material layers or oxide-nitride-based material layers containing an oxide of at least one element selected from the group GM consisting of Sn, Ga and Zn, and at least one of an oxide and a nitride of at least one element selected from the group GL consisting of Al, Si and B, or oxide-fluoride-based material layers containing a fluoride of at least one element selected from La and Ce, and one example of at least one of element selected from the group GM.
