Abstract: A data reader may have a magnetoresistive stack consisting of at least magnetically free and magnetically fixed structures. The magnetically fixed structure can be set to a first magnetization direction by a first pinning structure separated from an air bearing surface by a front shield portion of a magnetic shield. The front shield portion may be set to a different second magnetization direction by a second pinning structure.

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.
