摘要： A magnetic metal deposition material contained in a hearth is heated and evaporated in a vacuum to form a flow of vapor, which is then ionized and converged toward a predetermined deposition surface of a flexible substrate. The flexible substrate is moved obliquely downwardly along a convex course by sliding contact with the curved surface a fixed curved guiding body between a pair of guide rollers located at different heights above the hearth. The fixed curved guiding body communicates with a coolant source for cooling the substrate moving in contact therewith and may be provided with oscillators. Thus a thin film of the magnetic metal is deposited on the convex surface of the substrate.

摘要： In forming a vertical magnetization type recording medium, a first soft magnetic film layer is formed on each side of a film-shaped support by vacuum deposition or sputtering at a temperature of 30.degree. C. or lower, a second soft magnetic film layer is formed on each of the first soft magnetic film layers, and a vertical magnetization film layer essentially containing Co-Cr is formed on each of the second soft magnetic film layers. The thickness of the first soft magnetic film layer on one side of the support may be made different from that of the first soft magnetic film layer on the other side so that curling of the recording medium is substantially eliminated.

摘要： A magnetic recording medium and a process for producing it is disclosed. The medium is comprised of a non-magnetic flexible support base and a magnetic layer formed on a surface of the support base. The magnetic layer is preferably in the form of a thin, ferromagnetic metal film formed by vapor deposition. An overcoat layer of a fluorine-containing organic material is formed directly on the magnetic layer. The fluorine content of the overcoat layer continuously and gradually decreases in the direction toward the magnetic layer. Accordingly, high fluorine content near the surface of the overcoat layer provides improved smoothness near the surface whereas the lower fluorine content near the interface of the overcoat with the magnetic layer allows for strong adhesion between the overcoat and the underlying magnetic layer substrate. The media is formed by providing the flexible support base, forming the magnetic layer on the surface of the support base and forming the overcoat layer on the magnetic layer by performing plasma polymerizations of a fluorine-free monomer gas and a fluorine-containing monomer gas with a time lag. The overcoat layer is formed such that the fluorine content continually increases in a direction away from the magnetic layer.

摘要： A process for forming a vapor-deposited thin layer of organic material is disclosed. The process involves placing organic material on a support base within a vacuum chamber and providing a heat source in the vicinity of the organic material. A second support base is then provided within the vacuum chamber and heat is applied to the organic material at a temperature which causes the organic material to form vapors. The vapors are vapor-deposited on the second support base forming the thin layer of organic material. It is generally desirable to move both of the support bases during the vapor deposition process allowing the formation of a continuous uniform thin layer of organic material.
