Abstract

This paper reviews recent theoretical and experimental advances in disk/spindle vibrations that appear in computer hard disk drives. Four major arears are discussed: mathematical models, hydrodynamic spindles, instrumentation, and alternative disk media substrate.

Main text

For the past 20 years, the disk drive industry has continued to increase the track density (measured by tracks per inch, TPI) and the rotational speed (measured by revolutions per minute, RPM) in order to increase storage capacity and to reduce data access time. For high-TPI, high-RPM drives, disk and spindle vibration becomes a critical issue and a major concern. If the vibration exceeds an allowable limit called the track misregistration budget, read/write errors may occur. For drives with
