Abstract: A data reader may be configured at least with a magnetic stack that has a first magnetic layer separated from a second magnetic layer by a non-magnetic spacer layer. The first magnetic layer may have an areal extent on an air bearing surface (ABS) that differs from the second magnetic layer while the second magnetic layer can be configured with a first plurality of linear sidewalls that are each angled with respect to a second plurality of linear sidewalls of the first magnetic layer.
Abstract translation: 数据读取器可以至少配置为具有通过非磁性间隔层与第二磁性层分离的第一磁性层的磁性堆叠。 第一磁性层可以具有与第二磁性层不同的空气轴承表面（ABS）上的面积范围，而第二磁性层可以配置有第一多个线性侧壁，该第一多个线性侧壁各自相对于第二多个 第一磁性层的直线侧壁。

Abstract: A read head includes a bottom shield and a bottom isolation layer that electrically isolates the bottom shield. The read head includes left and right reader stacks having respective bottom layers disposed on at least a portion of the bottom isolation layer. The left and right reader stacks are cross-track adjacent to one another. The read head also includes left and right bottom contacts electrically coupled to respective left and right bottom layers. A top shield is configured as a common top contact electrically coupled to respective top layers of the left and right reader stacks.
Abstract translation: 读头包括电气隔离底部屏蔽的底部屏蔽和底部隔离层。 读头包括左和右读取器堆叠，其具有设置在底部隔离层的至少一部分上的相应的底层。 左和右读取器堆叠彼此相邻地交叉轨道。 读头还包括电耦合到相应的左底层和右底层的左和右底部触点。 顶部屏蔽被配置为电耦合到左和右读取器堆叠的相应顶层的公共顶部触点。
