Abstract: The application discloses a magnetic pole assembly having a pole tip arranged in a magnetic flux path and side shields separated from the pole tip by non-magnetic gap regions. The side shields are shaped to provide a differential shielding effect alongside the pole tip. As described, the sides shields are shaped to provide a non-magnetic gap region having a width that increases in the downtrack direction along a length of the pole tip. The increasing non-magnetic gap region alongside the pole tip provides a smaller non-magnetic gap region separating the pole tip from the side shields at the leading edge than the non-magnetic gap region separating the pole tip from the side shields at the trailing edge of the pole tip.

Abstract: A data storage device may have one or more data writers that are configured with at least one write pole and shield. The write pole and shield can each be positioned on an air bearing surface. The shield may have first and second protrusions each extending from a shield body towards the write pole with the first protrusion positioned on the air bearing surface and the second protrusion separated from the air bearing surface and first protrusion by a lateral notch.
