Tribology and Mechanics of Magnetic Storage Devices

Magnetic recording is presently a $50 billion industry. It spans audio, video, and digi­ tal applications in the form of tapes and disks. The industry is expected to grow by a factor of five or more in the next decade. This growth will be accompanied by dramatic improvements in the technology, and t...
