Abstract:
A GMR sensor is disclosed for sensing magnetically recorded information on a data storage medium. The sensor includes a ferromagnetic free layer and a ferromagnetic pinned layer sandwiching an electrically conductive spacer layer. An engineered overlayer is formed on the free layer to decrease free layer magnetic thickness without reducing physical thickness.
