Book excerpt: We present results of a study of hemispherical pins of manganese-zinc ferrite sliding against rigid disks composed of thin films of a sputtered cobalt-nickel-platinum alloy and carbon, with perfluoropolyether as the topical lubricant. The contact life, as marked by the total distance slid to the point at which the coefficient of friction increases rapidly over the steady state value, is much longer in air with 50 percent relative humidity than in dry air or vacuum. The wear debris generated in humid air is much finer and is enriched with cobalt on its surface. In dry air and vacuum, the debris is substantially larger than one micron and tends to be enriched with nickel on its surface. We present a hypothesis which explains the wear mechanisms in various operating environments.

Book excerpt: Since January 1990, when the first edition ofthis first-of-a-kind book appeared, there has been much experimental and theoretical progress in the multi disciplinary subject of tribology and mechanics of magnetic storage devices. The subject has matured into a rigorous discipline, and many university tribology and mechanics courses now routinely contain material on magnetic storage devices. The major growth in the subject has been on the micro- and nanoscale aspects of tribology and mechanics. Today, most large magnetic storage industries use atomic force microscopes to image the magnetic storage components. Many companies use variations of AFMs such as friction force microscopes (FFMs) for frictional studies. These instruments have also been used for studying scratch, wear, and indentation. These studies are valuable in the fundamental understanding of interfacial phenomena. In the second edition, I have added a new chapter, Chapter 11, on micro and nanoscale aspects of tribology and mechanics of magnetic storage compo nents. This chapter presents the state of the art of the micro/nanotribology and micro/nanomechanics of magnetic storage components. In addition, typographical errors in Chapters 1 to 10 and the appendixes have been corrected. These additions update this book and make it more valuable to researchers of the subject. I am grateful to many colleagues and particularly to my students, whose work is reported in Chapter 11. I thank my wife, Sudha, who has been forbearing during the progress of the research reported in this chapter.
