A ferromagnetic, high speed, sputtering apparatus is provided which comprises a vacuum chamber and a target of ferromagnetic material. The target comprises at least two segments which are positioned adjacent to one another and have a gap therebetween. This gap has at least a portion of which that does not extend in the direction of the thickness of the target. A substrate in the vacuum chamber is positioned facing one side of the target. Also, magnetic field generating means is positioned on the other side of the target so that the magnetic field therefrom leaks through the gap.

摘要:
A ferromagnetic, high-speed sputtering apparatus including an evacuable chamber, a substrate in the chamber, a target of ferromagnetic substance in the chamber facing the substrate, and magnetic field developing means in the chamber on the side of the target opposite the substrate. The target serves as a cathode. The target includes at least two separate segments of ferromagnetic substance which are spaced apart one from another by a gap so that a leakage magnetic field may be produced on the surface of the target facing the substrate. The gap may be less than about 3 mm. Each of the segments can include a ridge portion on the surface facing the substrate. Each ridge portion can have at least one apex and at least one slant surface.

摘要:
A thin film made of a conductive material is formed on one surface of a long-sheet-shaped flexible base. The flexible base formed with the thin film made of the conductive material is wound in a roll shape to fabricate an original roll of coils. The flexible base formed with the thin film made of the conductive material is unwound from the original roll of coils, and rewound around an outer periphery of a core to fabricate a wound body. The wound body is cut in a direction orthogonal to the longitudinal direction of the core to make a coil intermediary body. A cut surface of the coil intermediate body which is cut from the wound body is lapped. Lead wires are attached to both ends of a winding section comprised of the conductive material within the coil intermediary body. The foregoing steps are performed in sequence to manufacture a coil.

A magnetic head includes first and second cores joined into a one-piece member through a nonmagnetic spacer. A DGL head has a low saturation magnetic flux density thin film disposed between the first core and the nonmagnetic spacer. An EDG head further has a high saturation magnetic flux density thin film disposed between the second core and the nonmagnetic spacer in the DGL head structure. The low saturation magnetic flux density thin film is formed of an amorphous alloy preferably having a saturation magnetic flux density of 1,500 to 3,000 G.
