Abstract
A read sensor for use in a magnetic read head includes a magnetoresistive stack having a plurality of layers, and first and second shield regions positioned adjacent to the magnetoresistive stack. Each of the shield regions includes a first soft magnetic layer for shunting flux from an adjacent track to the shield region instead of the magnetoresistive stack.
