The method and system further include performing a high energy ion mill at an angle from a normal to the top of the main pole and at a first energy. The high energy ion mill removes a portion of the top of the main pole and exposes a top bevel surface for the main pole. The method and system also include performing a low energy ion mill at second energy and a glancing angle from the top bevel surface. The glancing angle is not more than fifteen degrees. The second energy is less than the first energy. The method and system also include depositing a nonmagnetic gap.
