    摘要: A magnetic device according to one embodiment includes a source of flux; a magnetic pole coupled to the source of flux, the magnetic pole having two or more gaps; and a low reluctance path positioned towards at least one of the gaps and not positioned towards at least one other of the gaps for affecting a magnetic field formed at the at least one of the gaps when the source of flux is generating flux. Other disclosed embodiments include devices having coil turns with a non-uniform placement in the magnetic yoke for altering a magnetic field formed at the at least one of the gaps during writing. In further embodiments, a geometry of the magnetic pole near or at one of the gaps is different than a geometry of the magnetic pole near or at another of the gaps to help equalize fields formed at the gaps when the source of flux is generating flux.

    摘要: A magnetic write head with a flux diverting structure for diverting stray flux received 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 diverting structure is proximate to the first pole and has a magnetic connection toward the back of the structure, and a non-magnetic separation toward the front of the structure. The flux diverting structure is comprised of a magnetic permeable material such that stray flux is diverted away from portions of the write head.
