ABSTRACT:
A method for making an enhanced spin valve sensor with engineered overlayer for sensing magnetically recorded information on a data storage medium. The method includes forming a ferromagnetic free layer and a ferromagnetic pinned layer sandwiching an electrically conductive spacer layer. An overlayer is formed on the free layer and adapted to decrease free layer magnetic thickness without reducing physical thickness.
