Abstract
A data reader may have a magnetoresistive stack consisting of at least magnetically free and magnetically fixed structures with the magnetically fixed structure set to a first magnetization direction by a pinning structure separated from an air bearing surface by a front shield portion of a magnetic shield. The pinning structure can meet the front shield portion with a planar sidewall angled at 10° or less with respect to the ABS.
