High magnetic moment seed layer materials for writer pole tips

The present invention relates generally to the field of magnetic data ea storage and retrieval. In particular, the present invention relates to high magnetic moment seed layer materials for use in forming a writer pole tip. A magnetic recording head has a magnetic pole tip and a seed layer upon which the magnetic pole tip is formed. The seed layer is preferably formed of a high magnetic moment material having a saturation magnetization of at least 1.8 Tesla and a high resistance to corrosion. In preferred embodiments of the present invention, the seed layer is preferably formed of 2.1 Tesla FeCoNi, 1.8 Tesla FeNiCoTesla FeCr, or 1.9 Tesla FeCoCr, wherein the subscripts indicate a preferred range of atomic percentages for each element in the given alloy.
