Friction–vibration interactions and applications in computer hard disk drive system


This chapter presents critical applications of friction–vibration interactions in computer hard disk drive systems. The present high storage capacity computer hard disk drive applies two nm spacing head-disk interface. At such a small clearance between slider and disk, friction/contact–vibration interactions are unavoidable, and the modeling, design and implementation of a stable interface are critical for hard disk drive products.

The chapter starts with a brief discussion of contact/friction-induced vibrations of air-bearing slider in hard disk drives. The air-bearing slider-disk system, nano-meter spacing interface analysis, contact model and ...
