Abstract: A method of forming a magnetic recording head. The method includes depositing a sacrificial metal alloy layer, which is wet etchable and has a moderate mill resistance, over a substrate. The method also includes depositing a write pole layer over the sacrificial metal alloy layer. The write pole layer has a bottom surface and a top surface opposite the bottom surface. A portion of the bottom surface of the write pole layer is in contact with the sacrificial metal alloy layer.
