Patent ID: 7007372

Claim:
A method for constructing an inductive write structure for use in a magnetic data recording system, comprising: forming a first magnetic pole of a magnetic material; depositing a first insulation layer; depositing a layer of dielectric write gap material; forming an electrically conductive coil; depositing a second insulation layer: curing said second insulation layer; forming a thin layer of high magnetic moment material, by sputter depositing a lamina of FeXN, X being selected from the group of materials consisting of Rh, Ta, Al, Ti, and Zr, and sputter depositing a lamina of a cobalt based ferromagnetic amorphous alloy; masking the thin layer of high magnetic moment material in a pattern corresponding to a second pole; plating a magnetic material in the pattern of said second pole; performing a first ion milling process, to remove at least a portion of the sputtered, high magnetic moment material not covered by the plated second pole; and after forming the first magnetic pole: forming a layer of a high magnetic moment material by sputter depositing onto said first pole; masking the high magnetic moment material formed onto the first pole in a pattern corresponding to a pedestal to be formed on an end of the first pole; and etching to remove said sputter deposited high magnetic moment material not covered by said mask to form said pedestal; wherein forming the layer of the high magnetic moment material on said first pole comprises depositing at least one lamina of the high magnetic moment material and at least one lamina of a non-magnetic, dielectric material.
