Abstract: A data reader may consist of at least a magnetoresistive stack positioned on an air bearing surface. A portion of the magnetoresistive stack may be set to a first fixed magnetization by a pinning structure separated from the air bearing surface by a front shield that is set to a second fixed magnetization by a biasing structure. The front shield may be separated from the biasing structure by a coupling structure.

Abstract translation: 数据读取器可以由位于空气轴承表面上的至少一个磁阻堆叠构成。 磁阻堆叠的一部分可以通过由空气轴承表面分离的钉扎结构设置为第一固定磁化，前挡板通过偏置结构设定为第二固定磁化。 前屏蔽件可以通过耦合结构与偏置结构分离。
