Abstract: PURPOSE:To compatibly obtain both of a high output characteristic and flawing property by specifying the average surface roughness on the magnetic layer side of metallic foil and the ratio between the average surface roughness of the surface not coated with the magnetic layer and the max. height to respectively specific ranges. CONSTITUTION:The magnetic recording medium is constituted by providing the magnetic layer on one surface of the metallic foil. The average surface roughness Ra on the magnetic layer side of this metallic foil is required to be 2 to 100nm and the ratio Rt/Ra between Ra of the surface not coated with the magnetic layer and the max. height Rt to be

Abstract: PURPOSE:To lessen double refraction and hygroscopicity and to improve transparency, heat resistance and molding workability by using specific transparent polyester as a base material. CONSTITUTION:The transparent polyester consisting of a dionyl unit having an arom. ring in the side chain and dibasic acid unit having an arom. ring in the main chain is used as the base material of an optical disk substrate. The dibasic acid is preferably terephthalic acid and/or isophthalic acid and >=50% of the acid component thereof is preferably the terephthalic acid and/or isophthalic acid. Arom. dibasic acids such as phthalic acid and diphenyl carboxylic acid are preferably used in combination so that the heat resistance of the resulted polymer is improved and the amorphous polymer is obtd. The diol component has the polystyrene deriv. segment of

Abstract: PURPOSE:To enhance the synthesizing velocity of a diamond-like thin film by performing sputtering vapor deposition while keeping carbon as a target under the existence of hydrocarbon having cyano radical. CONSTITUTION:Hydrocarbon contg. cyano group and an unsaturated C-C bond such as cyanoacetylene, dicyanoacetylene, acrylonitrile and methacrylonitrile is prepared. Sputtering vapor deposition is performed while keeping carbon as a target under the existence of hydrocarbon having one or more cyano group selected from among these. Thereby a diamond-like carbon thin film is quickly formed on a substrate.
