Popis: The generation of smears at head-disk interfaces operating at clearances in the range from 1–2 nm represents an increasing challenge- both to component designers as well as those interested in reliable operation of magnetic recording devices over extended periods. In this work, we examine the chemical and topographical nature of these smears, the experimental conditions under which they form and discuss methodologies to limit the generation of these smears. We discuss both “intrinsic” and “extrinsic” smears and highlight the importance of interface design in order to assure long term reliability.
