Abstract: A magnetic write head with a flux opposing structure for opposing stray flux from an external source. The write head includes a yoke with two poles and a non-magnetic gap formed there between, and functions to write data to a magnetic storage medium. The flux opposing structure is proximate to the first pole and has a separation from an exterior surface of the first pole. A current applied to the secondary coil to create a secondary flux field with an opposite polarity of a first magnetic flux. The secondary flux field opposes the stray flux associated with the primary flux field of the magnetic write head and/or a neighboring magnetic write head.

Abstract: A write head includes a first pole P1, a P1 pedestal, a first back gap layer plated on top of the first pole P1 leaving a region between the P1 pedestal and the first back gap layer for plating a coil. Further, a first insulation layer is applied on top of the P1 pedestal and the first back gap layer and the region between the P1 pedestal and the first back gap layer. The write head further includes a coil, patterned at least partially on top of the P1 pedestal and the first back gap layer and the region between the P1 pedestal and the first back gap layer, copper plated in the coil patterns, and a second insulation layer is applied to fill the spaces in between the coil turns. The resulting structure is planarized via chemical mechanical polishing.

Abstract: The present invention relates to a magnetic head and particularly to improvement of its recording element. The recording element includes a first magnetic film, a second magnetic film, a coil film, and an insulating film. The first magnetic film has a first pole portion. The second magnetic film has a second pole portion opposed to the first pole portion with a magnetic gap film therebetween and is joined to the first magnetic film at a back gap portion that is located in a rearward position with respect to a medium facing surface. The coil film extends around the back gap portion, and the insulating film encloses the coil film. Moreover, the second magnetic film entirely covers the insulating film.

Abstract: A thin film device is provided, in which inductance can be increased when a thin film coil wound on a magnetic film is provided. In a thin film coil wound on a magnetic film, thickness of lower coil portions is smaller than thickness of upper coil portions. Consequently, a magnetic property (permeability) tends to be hardly deteriorated.
