Described are magnetic recording heads that include auxiliary current wires that drive the write pole tip, augmenting the main coils that provide magnetomotive force to the write pole. The auxiliary wires are provided in close proximity to the write pole tip near the media-facing surface of the recording head, and are preferably in closer proximity to the write pole tip than are the main coils. In certain writer designs that include one or more heat sink structures positioned near or around the write pole tip, such as may be found in heat-assisted magnetic recording writer constructions, the auxiliary wire(s) may be accommodated near or around the heat sink structures, or the heat sink structures themselves can serve as the auxiliary wires.
