This book resulted from using, documenting and teaching various analysis

techniques during a 30-year mechanical engineering career in the disk drive

industry. Disk drives use high performance servo systems to control actuator

position. Both experimental and analytical techniques are used to understand

the dynamic characteristics of the systems being controlled. Constant in-

depth communications between mechanical and control engineers are required

to bring high performance electro-mechanical systems to market. Having

mechanical engineers who can discuss dynamic characteristics of mechanical

systems with servo engineers is very valuable in bringing these high-

performance systems into production. This book should be useful to both the

mechanical and control communities in enhancing their communication. -This book resulted from using, documenting and teaching various analysis
