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.
Claims11
A magnetic recording head comprising:
- a slider having a substrate, the substrate having a trailing end and an air bearing surface;
- a transducer formed on said trailing end of the substrate, the transducer having one or more magnetic poles comprising a magnetic alloy extending along said trailing end including one or more pole tips substantially flush with the substrate's air bearing surface;
- and
- said one or more magnetic poles each having a pole tip region just below the air bearing surface further including molecules selected from a group consisting of carbides, nitrides or borides.
A magnetic recording head comprising:
- a slider having an air bearing surface;
- and implanted ion means for improving the tribology between the air bearing surface and a magnetic recording medium.
