Tribology and Mechanics of Magnetic Storage Devices

The increasing demand for higher-density, highly reliable recordings within the magnetic recording industry requires a fundamental understanding of the tribology and mechanics of the magnetic head-medium interface. This first-of-its kind monograph offers a systematic compilation of current knowledge of tribology as applied to magnetic storage devices. It treats all important practical aspects including friction, interface temperatures, wear, lubrication, lubricants, and surface finishing (machining). The book first develops a fundamental understanding of the underlying physical mechanisms before addressing a diversity of practical applications. Wherever possible, theories and types of experimental measurements are discussed and compared for corroboration and to further understanding. In addition, the book incorporates ample experimental data, relevant properties of materials and surfaces, making the book more useful to engineers and scientists working in the field. It is intended for graduate students of tribology and mechanics research workers, and the practicing engineer who needs to solve quickly a tribological or reliability problem. Many of the theories presented are very general and applicable outside magnetic-storage systems.
