Claim 15:
16. A magnetic recording head assembly, comprising:
a magnetic recording head, the magnetic recording head comprising:
a lower pole,
an upper pole,
a conductive structure between the upper pole and the lower pole, the conductive structure comprising a main pole, a first side gap conductive layer, and a second side gap conductive layer, wherein each of the main pole, the first side gap conductive layer, and the second side gap conductive layer is formed of a conductive material;

a leading shield on a leading side of the conductive structure;
a trailing shield on a trailing side of the conductive structure; and
an alternating current (AC) source coupled to a first outer side of the conductive structure and a second outer side of the conductive structure to supply AC current horizontally through the conductive structure along a cross-track direction, wherein the second outer side opposes the first outer side along the cross-track direction.
