摘要: An apparatus and associated method provides a magnetic element, such as a data transducing head. A first permanent magnet may be configured to bias the write pole to decrease remnant magnetization and erasure after write (EAW). The first permanent magnet can be separated from the write pole be a predetermined distance.

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.
摘要翻译: 磁屏蔽与写柱相邻。 写入极具有主体部分和具有平行的第一和第二侧的延伸部分,每个第一和第二侧均以靠近空气支承表面(ABS)的预定角度向磁屏蔽倾斜。 延伸部分可以通过降低磁饱和度来增强磁屏蔽的写场梯度。

摘要: A write pole can have a magnetically conductive pole tip has at least one corner. The at least one corner may be chamfered to limit magnetic saturation of the conductive pole tip. The conductive pole tip can have one or more beveled surface that has a chamfered corner which extends a predetermined distance along an edge of the write pole.
