The MR sensor includes a plurality of generally parallel layers that form an MR stack. The MR sensor also includes a top shield and a bottom shield that are spaced apart on opposite sides of the MR stack in a longitudinal direction. The Mr sensor further includes a first and a second side shield spaced apart on opposite sides of the MR stack in a transverse direction. The top shield, bottom shield, first side shield and second side shield substantially surround the MR stack.
