摘要： A thin film magnetic head includes an integrally formed preconditioning gap (110) having a width greater than the write gap width (116) to precondition a magnetic media for the more accurate placement of magnetic transitions on a magnetic medium. The thin film magnetic head is comprised of a first extended pole piece (100) underlying a thin pancake helically wound magnetic coil (102) with a second pole piece (104) aligned with the first pole piece (100) and attached to it through the center of the coil. A third pole piece (106), aligned with the first two pole pieces (100 and 104), overlies all of the foregoing and is attached to the first pole piece (100) at its rearward end (108) to thereby cover the other underlying layers of this thin film structure. The single magnetic coil (102) surrounds the second pole piece (104) and energizes both gaps (110 and 116).

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.
