Abstract
The application discloses pole tip shield assemblies for a magnetic write element. The shield assemblies disclosed include side shields to limit adjacent track interference. The side shields are truncated or notched at a midpoint to form an expanded non-magnetic gap along a trailing portion of the pole tip to enhance write field and/or field gradient. The expanded non-magnetic gap region is larger than the non-magnetic gap region along a leading portion of the pole tip.
