摘要：
A magnetic shield is adjacent a write pole. The write pole has a body portion with a body thickness and an extension portion with parallel first and second sides that each tilt towards the magnetic shield at a predetermined angle proximal to an air bearing surface (ABS). The extension portion may be capable of enhancing a write field gradient of the magnetic shield by reducing magnetic saturation.
