Novel method to make a high data rate stitched writer for a giant magneto-resistive head

摘要

A high data-rate stitched pole magnetic read/write-head combining sputtered and plated high magnetic moment materials and a method for fabricating same. The plating and stitching aspects of this fabrication allow the formation of a very narrow write-head, while the sputtering permits the use of high magnetic moment materials having high resistivity and low coercivity.
