The present invention provides an optical information medium having excellent weather resistance and repeating characteristics. The optical information medium has a barrier layer between a protective layer and a recording layer. The barrier layer includes GeN or GeON, and at least one element selected from the group consisting of Al, B, Ba, Bi, C, Ca, Ce, Cr, Dy, Eu, Ga, H, In, K, La, Mn, N, Nb, Ni, Pb, Pd, S, Si, Sb, Sn, Ta, Te, Ti, V, W, Yb, Zn and Zr.

Optical information recording medium, producing method thereof and method of recording/erasing/reproducing information

An optical information recording medium of the present invention includes a protective layer; an interface layer; and a recording layer, the optical characteristics of which are changed reversibly when irradiated by a laser beam, layered in this order on a substrate. The protective layer contains at least Zn, S, and Si atoms, and an atomic composition ratio of O to Si is at least 0 and smaller than 2. A refractive index of the interface layer is smaller than a refractive index of the protective layer.

Optical information recording medium and its manufacturing method

A switch assembly () comprises a push-button section () and a push-button body () as an operation transmitting member, an LED box () and a contact-making contact () as a direct functioning member, and a communication-function incorporating contact (communications contact) () as an information input/output functioning member, as permitting these components to be connected with each other. Therefore, the switch assembly can respond to an operation given to the push-button body () by causing the contact-making contact () to provide an output for switching between a conductive state and a non-conductive state and by causing the communications contact () to output an information signal to a network.

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;/(n,&middot;k,)&lE;d,&lE;1.0 &lgr;/(n,&middot;k,), where n,is a refractive index and k,is an extinction coefficient of the light absorption layer.

A method for manufacturing an optical information recording medium having an excellent mechanical strength, thermal stability, and improved overwrite cycle property can be provided by forming the dielectric layer by using a mixed target comprising ZnS and SiO.sub.2 in an atmosphere comprising rare gas and at least oxygen at the side where the dielectric layer does not contact to the recording layer. The optical information recording medium is manufactured by using the substrate, the recording layer comprising a material that varies reversibly between the optically identifiable states by an irradiation of a laser beam, and the dielectric layer at least one side of which has a two-layered structure at the upper and lower sides of the recording layer. At least one of the dielectric layers that does not contact to the recording layer is formed by using a mixed target comprising ZnS and SiO.sub.2 in a mixed atmosphere comprising rare gas and oxygen.

Optical information recording medium and manufacturing method

A method for manufacturing an optical information recording medium which is usually stable and is not affected by the environmental condition and an apparatus used therefor. The method comprises the steps of placing a substrate and a member comprising a material for a film opposing each other in a vacuum film forming chamber; forming a plasma by glow discharging a gas between the substrate and the member comprising a material for a film; and supplying a gas mixture containing water to the film forming chamber before forming films or during forming films of the protective layer by the film forming method in which the material for a film freed from the member comprising a material for a film by using the plasma as an energy source are attached or deposited on the substrate.
