description	1. Field of the Invention A method employs an RF magnetron sputtering system under specific process conditions for making shield and pole piece ferromagnetic layers of a read write magnetic head wherein the magnetic anisotropy Hof the ferromagnetic layers is substantially maintained without easy axes switching when annealed along their hard axes in the presence of a magnetic field (hard axis annealing).
