Abstract
Techniques are disclosed for improving the tribology between an air bearing surface of a magnetic recording head and a magnetic recording medium. In addition, techniques are described for reducing resistance to wear and corrosion of the air bearing surface of the recording head as well as resistance to corrosion of the recording medium. Various ion beam techniques can be used to enhance the properties of the recording head and recording medium, and include ion implant techniques, ion mixing techniques and ion burnishing techniques.
