Abstract
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 Fe Co Ni , 1.8 Tesla Fe Ni Co Tesla Fe Cr , or 1.9 Tesla Fe Co Cr , wherein the subscripts indicate a preferred range of atomic percentages for each element in the given alloy.
