摘要

A data storage device employing a data writer may configure the data writer with at least a write pole that is separated from a front shield on an air bearing surface. The front shield can be arranged to continuously extend from the air bearing surface a first throat height distal the write pole and a second throat height proximal the write pole with the first and second throat heights being different.

主权项

1. An apparatus comprising a write pole disposed between first and second side shields and positioned uptrack from a front shield on an air bearing surface (ABS), the front shield continuously extending from the first side shield to the second side shield with a varying throat height that defines a shaped notch proximal a write pole tip of the write pole, the shaped notch separated from the ABS and having a first shield sidewall overlapping a first body sidewall of the write pole and a second shield sidewall overlapping a second body sidewall of the write pole, the first and second shield sidewalls each respectively overlapping only one body sidewall of the write pole.
