of the schematic drawings designated as fig1 through fig7 referring first to fig1 we have as a starting point for the fabrication of the present invention a planarized giant magneto resistive gmr read head comprising a lower magnetic shield 10 a first gap 15 the gmr field sensor 12 side pieces providing lead longitudinal bias 19 a second gap 17 an upper magnetic shield 14 of material such as nife coznta coznnb fealsi fealn or fetan which also serves as the lower pole piece of the write head to be fabricated and a dielectric or non magnetic metal medium 16 the upper surfaces 18 of the dielectric or non magnetic metal medium 16 and the upper magnetic shield 14 have been planarized by a method of chemical mechanical polishing cmp fig2 now shows the deposition of a first sputtered layer of high magnetic moment hmm magnetic material 20 on the planarized surface 18 this high magnetic moment material could be one of a group of materials such as fen fealn fetan cofe or conife and would be deposited with a thickness of between approximately 500 angstroms and 1 5 microns the upper shield 14 is shown here but all other components of the read head have been omitted for clarity fig3 shows the deposition of a write.
