Abstract
A method and system for providing a read magnetic transducer having an air-bearing surface (ABS) is described. The magnetic read transducer includes a first shield, a read sensor stack, an antiferromagnetic (AFM) tab, and a second shield. The read sensor stack includes a pinned layer, a spacer layer, and a free layer. The spacer layer is nonmagnetic and between the pinned layer and the free layer. A portion of the read sensor stack is at the ABS. The AFM tab is recessed from the ABS and adjacent to a portion of the pinned layer. The read sensor resides between the first shield and the second shield.
