Abstract: The present invention provides a thin film magnetic device realizing effective improvement in magnetic permeability in a high frequency area. The thin film magnetic device includes a thin film coil and a plurality of strip-shaped magnetic films disposed along a plane in which the thin film coil extends. The plurality of strip-shaped magnetic films are disposed to extend in one direction only in a pair of areas facing each other. The pair of areas is selected from four areas obtained by dividing, in the winding direction, the area where the thin film coil extends.

Abstract: In one embodiment and method of the present invention, a coil of a write head is created by forming a P1 pedestal layer and a back gap layer and further forming a coil pattern consistent with the coil to be formed and insulator spacers dispersed in the coil pattern, using a non-damascene process, thereafter the coil is formed by plating using a damascene process.

Abstract: A wire gap film is formed on a flat coplanar surface formed on a bottom pole by a bottom track pole and a thin film coil, first and second magnetic material films constituting a top pole are formed on a flat surface of the thin film coil, and the first and second magnetic material films, write gap film and bottom track pole are partially removed forming a top track pole and trim structure. The thin film coil is formed by first and second thin film coil halves having self-aligned coil windings and have a CVD formed first conductive film, and an electrolytic plating formed second conductive film. A thin insulating film is interposed between successive coil windings of the first and second thin film coil halves. Jumper wirings, formed with the top pole, connect innermost and outermost coil windings of the first and second thin film coil halves respectively.

Abstract: A thin film magnetic recording head comprises a substrate, a first magnetic core formed on the substrate, a second magnetic core having the front end face with a magnetic gap with respect to the front end face of the first magnetic core, and a coil for developing magnetic flux between the front end portions of the magnetic cores. A width of the second magnetic core at the front end portion thereof is chosen to be smaller than that of the first magnetic core. The second magnetic core is at a leading position relative to the second magnetic core in a traveling direction on a recording medium. In such configuration, it is possible to reduce side erase due to recording magnetic flux fringing and to achieve high density of magnetic recording while maintaining the conventional fabrication steps for the thin film magnetic recording head, thereby avoiding the problem in the fabrication.
