摘要
A magnetic device according to one embodiment includes a source of flux and a magnetic yoke coupled to the source of flux. The source of flux includes a thin film coil having multiple turns. The magnetic yoke has a pole with two or more gaps, wherein the coil turns have a non-uniform placement in the magnetic yoke for creating a higher magnetic field at one of the gaps than another of the gaps during writing. A magnetic device according to another embodiment includes a source of flux. 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.
