    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.
