A magnetoresistive (MR) head including, for example, a spin valve (SV) MR element having a sense current passing through the SV in a current-perpendicular-to-the-plane (CPP) mode. A free layer of the SV is transversely biased by a magnetostatic coupling field from an in-stack transverse bias layer.
