A write head includes a write return yoke, a write yoke connected to the write return yoke, conductive coils surrounding the write yoke, a write pole tip, and a non-magnetic spacer connecting the write pole tip to the write yoke. The non-magnetic spacer allows for reducing a magnetization of the write pole tip due to a remnant magnetic field in the write yoke. In another embodiment, the write head comprises a write shield, a write return yoke, a write yoke, conductive coils, a write pole tip, and a saturable yoke shunt connecting the write pole tip and the write shield. The saturable yoke shunt directs a limited amount of magnetic flux from the write pole tip to the write shield, such that when there is a remnant magnetic field in the write pole tip, the magnetic flux is directed to the write shield rather than to a disk.
