Abstract: A writer includes a leading edge, a trailing edge, a longitudinal axis defined between the leading and trailing edges, and a transverse axis orthogonal to the longitudinal axis. A writer region is provided at a protruded section of the trailing edge oriented along the longitudinal axis. A write pole is arranged at the protruded section to write data to two locations spaced apart from one another relative to the transverse axis for a range of skew angles.

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.
