T-shaped write pole

摘要

A magnetic element may be generally configured with at least a write pole that has leading and trailing regions on an air bearing surface. The leading region may have a trailing width connected to a leading width of the trailing region via a transition feature to form a substantially T-shaped cross-section on the air bearing surface.

主权项

1. An apparatus comprising a write pole comprising leading and trailing regions on an air bearing surface (ABS), the leading region having a leading width measured between first and second pole sidewalls on the ABS, the leading region connected to the trailing region via a transition feature to form a substantially T-shaped cross-section on the ABS, the trailing region having a trailing width measured from a third pole sidewall across first and second protrusions to a fourth pole sidewall of the write pole.
