Abstract
A magnetic element has a magnetically responsive lamination with a ferromagnetic free layer separated from a synthetic antiferromagnetic (SAF) layer by a spacer layer and from a sensed data bit stored in an adjacent medium by an air bearing surface (ABS). The lamination is coupled to at least one antiferromagnetic (AFM) tab a predetermined offset distance from the ABS.
