    摘要： In a multilayered recording medium, when a titanium oxide layer is formed using a sheet-type sputtering device, a transmittance significantly varies due to variations in thickness of the titanium oxide layer. Therefore, according to the present invention, in the multilayered recording medium having the titanium oxide layer, a second dielectric layer composed of titanium oxide, or mainly composed of the same, is formed on a first dielectric layer composed of niobium oxide or silicon dioxide, or mainly composed of the same. Further, when the sheet-type sputtering device is used, at least one chamber for promoting removal of water and oxygen from a substrate is provided between a load lock chamber and a chamber for forming a transmittance adjustment layer.

    摘要： 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.
