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.

A data storage device may be configured at least with a magnetic stack that contacts a magnetic shield. The magnetic stack can be disposed between first and second side shields and having at least one layer constructed of a CoFeNiB material. The magnetic shield may have a synthetic antiferromagnet with a non-magnetic layer disposed between first and second ferromagnetic layers.
