Abstract
An apparatus for cooling a nanowire in a wire assisted magnetic recording head using a radiator in close proximity to a shield of the write pole. The radiator may further contain current restraints (e.g., slits, cuts, or resistive materials) that maximize current density in the nanowire at a location that corresponds to the current restraints. These current restraints may be further arranged to align with a write pole such that the current is forced to flow primarily through the nanowire when the nanowire is closest to the write pole. The nanowire may then be used either as main or auxiliary writing element for recording signals to a high coercivity media. Moreover, the nanowire and radiator may be combined into a single nanofoil which has a least two portions that perform a similar function as both the nanowire and radiator.
