Abstract
The present disclosure generally relates to a magnetic recording system comprising a magnetic recording head that provides a low resistance cross-track current path at the trailing side of the main pole. A bias current may be driven through the path to enhance the magnetic write field to the magnetic recording media. The current is driven by an alternating current (AC) source external to the head. In some embodiments, the cross-track current going through the low resistance path enables high amounts of current to be utilized without break down of the magnetic recording head.
