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.
摘要翻译：包括磁极尖端屏蔽件的写入元件被公开。在所公开的实施例中，例如，磁极尖端屏蔽件包括由渐变磁矩材料制成的侧屏蔽部分，以形成渐变侧屏蔽部分，所述渐变侧屏蔽部分具有沿向下磁道方向沿着侧屏蔽部分的长度延伸。在另一个实施例中，极尖屏蔽件包括侧屏蔽部分，该侧屏蔽部分具有沿着极尖端的侧边缘的部分长度延伸的缩短的长度。在所示实施例中，侧屏蔽部分由成形体在极尖的前缘的前方具有凹入部分。凹入部分具有圆形凹入表面轮廓，其形成圆形轮廓，用于磁极尖端前缘前方的磁极尖端屏蔽的前缘部分之间的间隙区域。
