Abstract
An electromagnetic read/write system includes a contact interface formed by a pole-structure-carrying wear pad and a recording surface. The uppermost portion of the recording surface is characterized by a buffed, generally planarized topography. Lower elevations of the recording surface may be texturized or untexturized. Various methods of producing such an interface are described. The interface of the present invention provides dramatically improved longevity, i.e, wear performance through long term read/write operation.
