Abstract:
A high data-rate stitched-pole magnetic read/write-head combining sputtered and plated high magnetic moment (HMM) materials, comprising:a planarized GMR read-head positioned between a lower magnetic shield and an upper magnetic shield; a three-layer structure formed on the upper magnetic shield of the read-head, comprising a first sputtered HMM material layer, over which is a patterned write-gap layer and over which is a second sputtered HMM material layer which is patterned and wherein said sputtered HMM material layers are formed of the HMM material FeAlN, CoFeV, CoFe or CoNiFe deposited to a thickness of between 500 angstroms and 1.5 microns; a plated pole piece consisting of HMM material formed on the patterned second sputtered HMM material layer of the three layer structure and trimmed to its dimensions; a final pole piece stitched to the structure.
