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.
