Abstract: A perpendicular write head includes a main pole, a return pole, and conductive coils. The main pole includes a seedlayer and a magnetic layer that is plated upon the seedlayer. The seedlayer is nonmagnetic, electrically conductive, and corrosion-resistant. The return pole is separated from the main pole by a gap at an air bearing surface of the write head and is coupled to the main pole opposite the air bearing surface. The conductive coils are positioned at least in part between the main pole and the return pole.

Abstract: The present invention is directed to a corrosion resistant ferromagnetic alloy suitable for use as write pole material in on a magnetic media recording head, as well as to magnetic media heads containing the corrosion resistant alloy. The corrosion resistant film generally includes a rhodium-containing alloy, most typically a cobalt iron rhodium alloy. The invention is further directed to methods of forming the alloy and applying it to substrates, such as magnetic media recording heads. The corrosion resistant alloy provides significant corrosion resistance while simultaneously maintaining a high magnetic moment (Bs), which facilitates high density read and write functions.
