ABSTRACT:
A magnetic head including a flux closure layer that functions with a magnetic shield layer to reduce the flow of magnetic flux from the edge of the magnetic shield to an MR sensor element of the magnetic head. The flux closure layer is disposed adjacent to the magnetic shield to prevent magnetic flux leakage from the edges of the magnetic shield from flowing to the MR sensor element and create unwanted signal noise.
