    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).

    Abstract: An optical information recording medium including three or more information layers, wherein at least one information layer provided on the light incident side is an information layer which enables information to be overwritten and includes a recording film, a transmittance adjusting film of a dielectric containing Bi, Ti and O, and an isolation film in this order from a light incident side; and the isolation film is provided between and adjacent to the transmittance adjusting film and an intermediate separation layer which separate the information layer from another information layer on the side opposite to the light incident side; and the isolation film has an optical constant at a wavelength of 405 nm such that a refractive index is 1.8 or less and an extinction coefficient is 0.05 or less. This information recording medium prevents the repeated overwriting characteristics in a sever environment from being deteriorated.
