摘要： An information recording medium having such a recording material layer on a substrate where reversible phase change between electrically or optically detectable states can be caused by electric energy or electromagnetic energy. The recording material forming the recording layer is either a material having a crystal structure including lattice defects in one phase of the reversible phase change or a material having a complex phase composed of a crystal portion including a lattice defect in one phase of the reversible phase change and an amorphous portion. Both portions contain a common element. A part of the lattice defects are filled with an element other than the element constituting the crystal structure. The recording medium having a recording thin film exhibits little variation of the recording and reproduction characteristics even after repetition of recording and reproduction, excellent weatherability, strong resistance against composition variation, and easily controllable characteristics.

摘要： An information recording medium ensures high reliability and favorable overwrite cycle-ability even when an interface layer is not provided between a recording layer and a dielectric layer. The recording layer and the dielectric layers are formed on the surface of the substrate. In the recording layer, a phase change is generated between a crystal phase and an amorphous phase by irradiation of light or application of electric energy. The dielectric layers are oxide-fluoride-based material layers containing one or more oxides which each are an oxide of at least one element selected from a first group including only Ti, Zr, Cr, Hf, Nb, Ta, Cr and Si and one or more fluorides which each are a fluoride of at least one element selected from a second group including only La, Ce, Pr, Nd, Gd, Dy, Ho, Er and Yb.

摘要： An optical information recording medium includes a first information layer, a separating layer, a second information layer and a protective substrate in this order on a transparent substrate. The second information layer comprises an optical interference layer, a lower protective layer, a recording layer, an upper protective layer, and a reflective layer in this order from the side near the transparent substrate. The reflective layer has a refractive index of at least 2.5 at a wavelength &lgr; of light beams. The second information layer is a reflectance-increase type where the reflectance with respect to the light beams incident from the transparent substrate side after recording is higher than that before recording. It is possible not to provide the optical interference layer if the ratio n1/n2 of the refractive index n1 at the wavelength &lgr; of the recording layer before recording to the refractive index n2 thereof after recording is not more than 0.8.
