A magnetoresistive read element with improved biasing of the free layer is
disclosed. The read element includes a free layer, a spacer layer, a
first pinned bias layer, an APC layer, and a second pinned bias layer
antiparallel exchange coupled with the first pinned bias layer. The
second pinned bias layer has a width greater than the width of the first
pinned bias layer, while the volumes of the first and second pinned bias
layers are substantially similar. The width of the first pinned bias
layer allows magnetic fields from the first pinned bias layer to
longitudinally bias the free layer. The width of the second pinned bias
layer avoids magnetic fields of the second pinned bias layer from biasing
the free layer.
