A multilayer information recording medium is provided which has both good reproducing performance and good recording and rewriting capabilities as well as good repeated rewriting capabilities even after being archived for a long period of time. The information recording medium (22) has at least a first recording layer (104) and a second recording layer (204), which generate reversible phase changes between the crystalline phase and the amorphous phase. The first recording layer (104) contains Ge, Te and Bi, while the second recording layer (204) contains Sb and one or more elements M1 selected from a group consisting of V, Mn, Ga, Ge, Se, Ag, In, Sn, Te, Pb, Bi and Au. <IMAGE> |
