摘要： When manufacturing a write-once recording medium which contains an oxide having a lower oxygen content as a main component, if film formation of a recording layer is performed by introducing a large amount of oxygen into the film forming gas and the sputtering target does not contain oxygen, each medium produced has different properties, because a variation of oxygen flow in the gas easily occurs and the composition ratio of oxygen which is contained in the recording layer easily varies. To solve the problems above, an information recording medium, having at least a recording layer on a substrate and being able to record and reproduce information, contains an oxide A-O or A-O-M (A is a material which contains at least any one of Te, Sb, Ge, Sn, In, Zn, Mo and W, and M is a material which contains at least any one of a metal element, a semi-metal element, and a semiconductor-metal element), and a sputtering target used in the process of producing the layer contains at least A-O and, A and/or M. In this way, a recording layer having high reproducibility and stable properties can be produced, even in a mass production line.

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.

This optical information recording medium comprises a substrate having a groove and a land provided between adjacent grooves and a recording layer that is provided on the substrate and that changes the reflectance by irradiation with light beams. In this recording medium, the reflectance after recording is greater than the reflectance before recording. Moreover, the depth D of the groove is set to be in the range of &lgr;/8n to 3&lgr;/8n, where the wavelength of the light beam is &lgr; and the refractive index of the substrate is n.

摘要： An optical information recording medium of the present invention includes a transparent substrate and a multi-layered film formed on the transparent substrate. The multi-layered film includes a lower protective layer, a recording layer that changes reversibly between different states detectable optically by irradiation of light beams, an upper protective layer, an intermediate layer and a reflective layer in this order from the side near the transparent substrate. Of the upper protective layer, the intermediate layer and the reflective layer, the heat conductivity of the layer closest to the recording layer is the smallest of the three layers, and thereafter the heat conductivities of the others increase with increasing the distance from the recording layer, and the thickness of the recording layer is from 4 nm to 16 nm. In addition, a light absorption layer can be used in place of the intermediate layer. In this case, the difference between the refractive index of the light absorption layer and the refractive index of the reflective layer is 2 to 6, and the thickness of the reflective layer is not smaller than the thickness of the light absorption layer. Alternatively, the light absorption layer has a thickness d, in a range of 0.1 &lgr;/(n1·k1)≦d1≦1.0 &lgr;/(n1·k1), where n1 is a refractive index and k1 is an extinction coefficient of the light absorption layer.
