| 主权项 | 1. A write head, comprising: a yoke having at least a first gap and a second gap; and a coil configured to produce a magnetic field at each gap, the coil comprising a plurality of windings; wherein the windings are arranged with a changing intra-coil winding density so as to produce one of: a same magnetic field strength at each gap, and a same magnetic field strength along each gap, by use of a proximity effect between the windings and a respective gap. | ||
