Patent ID: 8177955

Claim:
A method of forming a magnetic layer on a substrate in a write head, comprising: (a) providing a substrate having a top surface aligned perpendicular to an air bearing surface (ABS); (b) forming a seed layer on said substrate, said seed layer has a composition represented by Fe W Co X Ni Y V Z in which w, x, y, and z are the atomic % of Fe, Co, Ni, and V, respectively, and where w is between about 60 and 85, x is between about 10 and 30, y is between 0 and about 20, z is between about 0.1 and 3, and wherein w+x+y+z=100; and (c) electroplating said magnetic layer on said seed layer in an electroplating cell wherein said magnetic layer contacts said ABS and has a composition essentially the same as that of said seed layer.
