ABSTRACT:
A perpendicular magnetic recording head comprises a write pole having a pole tip adjacent to an air bearing surface, a return pole, a pedestal for magnetically coupling the write pole to the return pole, a coil for inducing magnetic flux in the write pole, and a shield for coupling magnetic flux from the coil to the return pole. Disc drives that include such recording heads are also provided.
