摘要： PROBLEM TO BE SOLVED: To provide a sputtering device capable of a stable film deposition and requiring no complicated mechanical operation and to provide a magnetic recording medium small in the dispersion of coating thickness and the trace of arc discharge by using this device (e.g. a plasma CVD device). SOLUTION: This sputtering device is the one in which on a substrate 21 arranged opposite to a reaction tube 5 introducing gas 8 contg. a film forming material, film forming material (diamond-like carbon in particular) produced by a cracking of the gas 8 is deposited. In this case, the reaction tube 5 is formed of a material in which the coefficient of linear expansion is regulated to 33×10 or below (at 20 deg.C). Furthermore, by using this device (e.g. a plasma CVD device), carbon protective film or the like is stably formed.

摘要： PURPOSE:To improve corrosion resistance by forming a thin ferromagnetic metallic film on a nonmagnetic base and depositing an arom. diol salt on the thin ferromagnetic metallic film. CONSTITUTION:The thin ferromagnetic metallic film is formed on the nonmagnetic base and the arom. diol salt is deposited on the thin ferromagnetic metallic film. The arom. diol salt to be used as a rust inhibitor is a compd. prepd. by neutralizing an arom. cyclic diol with a base and is expressed by formula I. Formation of rust on the surface of the thin ferromagnetic metallic film which is a magnetic layer is thereby prevented even when the medium is subjected to a high temp. or high humidity. The deterioration in the magnetic characteristics such as coercive force and quantity of saturation magnetization with age is decreased as well.

摘要： PURPOSE:To reduce the friction coefficient of the titled medium by forming a lubricant layer contg. the perfluoroalkyl ester of a carboxylic acid and a rust preventive agent on a ferromagnetic metallic thin film as a topcoat layer. CONSTITUTION:The ferromagnetic metallic thin film 2 is formed on a nonmagnetic carrier 1, and the topcoat layer 3 consisting of the perfluoroalkyl ester of a carboxylic acid and a rust preventive agent is formed on the ferromagnetic metallic thin film. Phenols, naphthols, quinones, diaryl ketones, a heterocyclic compd. contg. a nitrogen atom, a heterocyclic compd. contg. an oxygen atom, a heterocyclic compd. contg. a sulfur atom, a compd. having a mercapto group, a thiocarboxylic acid or its salt, a thiazole compd., etc., can be exemplified as the rust preventive agent. As a result, a magnetic recording medium having excellent traveling stability, wear resistance, corrosion resistance, and long-period stability can be obtained.

摘要： PURPOSE:To maintain a lubicating effect for a long period of time and to obtain a medium which obviates the deterioration of durability by depositing and forming lubicating layers contg. the same kind of lubicating agents on a thin ferromagnetic metallic film and back coat layer. CONSTITUTION:The lubicating agent layers 4, 5 are respectively deposited and formed on the thin ferromagnetic metallic film 2 and back coat layer 3 of a magnetic recording medium. The lubicating agent layer 4 and the lubicating agent layer 5 contain the same kind of the lubicating agent. Known lubicating agents such as, for example, fatty acid, fatty acid ester, paraffin and silicone are usable as the lubicating agent to be used for the lubicating layers 4, 5. Since the back coat layer consists of an org. high polymer, inorg. etc. and is porous, the lubicating agent is filled into the fine pores of the back coat layer by forming the lubicating agent layer contg. the same kind of the lubicating agent as for the thin ferromagnetic metallic film on the back coat layer as well, by which the transfer and absorption of the lubicating agent from the surface of the thin ferromagnetic metallic film to the back coat layer is suppressed.
