Abstract
A method for manufacturing a magnetic write head having a leading magnetic shield and a trailing magnetic shield that are arranged to prevent the lost of magnetic write field to the trailing magnetic shield. The write head includes a non-magnetic step layer that provides additional spacing between the trailing magnetic shield and the write pole at a region removed from the air bearing surface.
