ABSTRACT:
A magnetic spin valve sensor is provided which has antiparallel coupled end tabs to magnetically stabilize the free layer. The antiparallel coupled bias stabilization tabs include antiferromagnetic layers which are laterally recessed from the ends of the ferromagnetic bias layers. A disk drive is provided having the novel spin valve sensor as the read element.
