摘要： A write element including a pole tip shield is disclosed. In embodiments disclosed, for example, the pole tip shield includes side shield portions fabricated of a graded magnetic moment material to form graded side shield portions having a magnetic moment that decreases in the down-track direction along a length of the side shield portions. In another embodiment, the pole tip shield includes side shield portions having a shortened length extending along a partial length of side edges of the pole tip. In illustrated embodiments, the side shield portions are formed of a contoured body having an indented portion forward of the leading edge of the pole tip. The indented portion has a rounded indented surface contour forming a rounded profile for a gap region between a leading edge portion of the pole tip shield forward of the leading edge of the pole tip.

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.
