Claim 20:
21. A magnetic recording head assembly, comprising:
a magnetic recording head, the magnetic recording head comprising:
a lower pole,
an upper pole,
a main pole between the upper pole and the lower pole,
a leading shield on a leading side of the main pole,
a trailing shield on a trailing side of the main pole, and
a conductive structure between the main pole and the trailing shield, wherein the conductive structure is of a width along a cross-track direction that is about equal to a trailing width of the main pole along the cross-track direction, the conductive structure comprising a conductive layer, wherein the conductive layer is nonmagnetic; and

an alternating current (AC) source coupled to the main pole and the upper pole of the magnetic recording head.
