    摘要: A base material excellent in heat resistance and high-temperature strength is processed into a desired configuration. The processed base material is coated with a heat-resistant film having excellent strength at high temperatures and low reactivity with a glass material to be molded. A resist is applied on the heat resistant film and a desired pattern is drawn thereon by means of electron beam, ion beam, hologram exposure, or ordinary photolithography. Or if a mold having deep unevenness of the pressing surface is required, the resist is applied after an intermediate layer which permits selective etching is formed on the heat resistant film, and the required pattern is drawn thereon by means of electron beam, ion beam, hologram exposure, or ordinary photolithography. The intermediate layer is removed by wet etching or dry etching to emphasize unevenness of the mask. The resist film or the resist film and intermediate layer film are completely removed and a part of the heat-resistant film is removed to obtain a mold having the desired configuration of the molding surface.

    摘要: A magnetic recording medium, comprising; a 2-layer film formed on a glass disk substrate as an under layer composed of an amorphous oxide or NaCl oxides like a NiO or CoO and the like, or any soft magnetic oxide of Mn-Zn ferrite, Ni-Zn ferrite and the like, or a combination of those 2 materials; a magnetic recording medium formed thereon composed of a Co ferrite perpendicular magnetic film of a columnar structure; and a structure formed thereon with a lubricant layer medium. This magnetic recording medium is used for a magnetic rigid disk apparatus. The substrate is made by press-molding the glass plate at a high temperature. The under layer film and Co ferrite film are composed of vapors of organic material compounds and oxygen as their raw materials, and made by a plasma assisted CVD method.

    摘要: A die for press-molding an optical element with high precision comprises a base material made of a material excellent in heat resistance, heat shock resistance and mechanical strength at high temperature, an intermediate layer formed on the base material and made of a thin film excellent in grinding machinability and cutting machinability, and a surface protective layer formed on the intermediate layer and made of a metal thin film excellent in heat resistance and mechanical strength at high temperature and less reactive to a material of the optical element. Additional thin film may be inserted between the base material and the intermediate layer so as to enhance the adhesion strength between the base material and the intermediate layer. In place of the additional thin film to be inserted, a peripheral flange part of the intermediate layer is removed and thus on the removed peripheral part, the surface protective layer is directly adhered to the base material.
