Abstract:
An information recording medium (9) of the present invention is an information recording medium with respect to which information can be recorded or reproduced by irradiation with an optical beam (1). The information recording medium (9) includes a second interface layer (103), a recording layer (104) and a first interface layer (105) in this order from the optical beam (1) incident side. The first interface layer (105) and the second interface layer (103) are disposed in contact with the recording layer (104). The second interface layer (103) contains M1 (where M1 is at least one element selected from Nb, Y, Dy, Ti, Si and Al), Cr and oxygen (O). The first interface layer (105) contains M2 (where M2 is at least one element selected from Nb, Y, Dy, Ti, Si, Al, Zr and Hf), Cr and oxygen (O). The first interface layer (105) and the second interface layer (103) each contain Cr in a range of 50 mol % or less in terms of the oxide (Cr2O3).
