A method for producing a magnetic recording medium includes the steps of causing a polymer film having a vapor-deposition surface to run; vaporizing a ferromagnetic metal material; depositing a thin film including the ferromagnetic metal material to the vapor-deposition surface of the polymer film in a vapor-deposition area where the polymer film runs with a tilt angle, with respect to a horizontal direction, in the range of about 20 degrees or more and about 80 degrees or less by oblique vapor deposition.

Magnetic recording medium method and apparatus for producing the same

A method and a device for manufacturing a thin film by a vacuum deposition method, and a magnetic recording medium produced thereby are disclosed. A thin film of high quality is mass-produced while introducing reaction gas to a thin film forming section from a nozzle consisting of minute tubes, so that the flow of evaporated atoms is not disturbed by the reaction gas.

Magnetic recording medium with a magnetic layer having a specific oxygen

A magnetic recording media is manufactured which includes a composite polymer film, which is formed of a flat surfaced polymer film and both inorganic particles and organic particles dispersed on and attached to the surface of the polymer film, and a magnetic film disposed over the particles which are attached on the surface of said composite polymer film. The magnetic recording media satisfies the performance requirements of magnetic recording media in a balanced manner including electromagnetic conversion characteristics, picture drop out performance, and running characteristics of magnetic recording tapes, and at the same time maintaining the foregoing performance characteristics even after repeated use of the magnetic recording tapes.

Magnetic recording media and manufacturing method thereof

In a method for manufacturing a functional thin film by a vacuum evaporation method, during a thin film containing a material is evaporation-deposited on a substrate, a gas flow controls orientation of the material in a manner that the gas flow substantially intersects direction of flow of vapor of said material onto the substrate.

Method for manufacturing functional thin film

A catalyst for exhaust gas purification comprises a carrier consisting of acid- and high temperature-resistant silica fibers, a first silica layer deposited on surfaces of the silica fibers, and a second heat-resistant material layer deposited on surfaces of the first silica layer, and a catalyst of noble metals, metals or metal oxides deposited on surfaces of the carrier.
