Abstract: Various embodiments may be generally directed to a magnetic element capable of reading magnetic data bits. Such a magnetic element may have at least a magnetic stack laterally adjacent a side shield and non-magnetic pedestal on an air bearing surface (ABS). The non-magnetic pedestal can be configured to have a greater stripe height from the ABS than the side shield.

Abstract: Various embodiments may position a side shield adjacent to and separated from a stack sidewall of a magnetic stack with the side shield having a shield layer disposed between the stack sidewall and a permanent magnet. The permanent magnet can be separated from a first portion of the shield layer by a diffusion barrier that decouples the permanent magnet from the shield layer.
Abstract translation: 各种实施例可以将侧屏蔽件定位成与磁性堆叠件的堆叠侧壁相邻并与之分离，其中侧屏蔽件具有设置在堆叠侧壁和永磁体之间的屏蔽层。 永磁体可以通过使永磁体与屏蔽层分离的扩散阻挡层与屏蔽层的第一部分分离。
