ABSTRACT:
A spin valve sensor with an antiparallel coupled lead/sensor overlap region is provided comprising a ferromagnetic bias layer antiparallel coupled to a free layer in first and second passive regions where first and second lead layers overlap the spin valve sensor layers. The ferromagnetic material of the bias layer in a track width region defined by a space between the first and second lead layers is converted to a nonmagnetic oxide layer allowing the free layer in the track width region to rotate in response to signal fields from a magnetic disk.
