    摘要： A thin film comprising titanium oxide as its main component, wherein the thin film includes titanium, oxygen and copper, content of Ti is 29.0 at% or higher and 34.0 at% or less and content of Cu is 0.003 at% or higher and 7.7 at% or less with remainder being oxygen and unavoidable impurities, and ratio of oxygen component to metal components, O/(2 Ti + 0.5 Cu), is 0.96 or higher. This invention aims to obtain a thin film comprising titanium oxide as its main component with a high refractive index and low extinction coefficient and a sintered compact sputtering target comprising titanium oxide as its main component which is suitable for producing the foregoing thin film, to obtain a thin film with superior transmittance and low reflectance and which is effective as an interference film or protective film of an optical information recording medium, and to obtain a thin film that can be applied to a glass substrate; that is, a thin film that can be used as a heat ray reflective film, antireflection film, and interference filter.

    摘要： [Object] To provide an optical recording medium that can be applied to a write-once optical recording medium having a high capacity of about 25 GB per one layer, and has good recording properties when a multilayered recording layer configuration is provided.
    [Solving Means] It includes a substrate 21 and two to four recording layers 221 and 222. At least one or more of these recording layers 221 and 222 are specific recording layers with a composition containing PdO and PdO 2 as well as at least one of completely oxidized In, Zn, Al and Sn (in other words, In 2 O 3 , ZnO, Al 2 O 3 and SnO 2 ). Adjacent to the specific recording layers, dielectric layers 232a and 232b of In/Al oxide layers containing at least either of In or Al as a main component are disposed.
