Abstract
A recording head for use with a magnetic storage medium includes a pair of write poles structured and arranged to apply a magnetic write field to the magnetic storage medium and a pair of oppositely directed conductors located adjacent the pair of write poles. The pair of conductors combine to induce the magnetic write field in the pair of write poles. One of the oppositely directed conductors has a positive voltage relative to ground and the other of the conductors has a negative voltage relative to ground, such that the pair of oppositely directed conductors combine to drive the magnetic write field in the same direction. Each of the conductors may be a microstrip waveguide.
