Abstract
A write pole can have a magnetically conductive pole tip has at least one corner. The at least one corner may be chamfered to limit magnetic saturation of the conductive pole tip. The conductive pole tip can have one or more beveled surface that has a chamfered corner which extends a predetermined distance along an edge of the write pole.

An apparatus comprising a magnetically conductive pole tip comprising a write surface positioned on an air bearing surface (ABS) and a beveled surface connecting the write surface with a top surface extending orthogonal to the ABS, the bevel surface having at least one chamfered corner.
A magnetic writing element comprising a beveled surface of a magnetically conductive pole comprising a write surface positioned on an air bearing surface (ABS) and connected to a top surface extending orthogonal to the ABS and first and second side surfaces by a beveled surface, the beveled surface having a first corner and first edge formed by the intersection of the first side surface and the top surface, at least the first corner and edge continuously chamfered away from the ABS.
