Abstract
An algorithm to design servo systems for future magnetic disk drives has been developed. An optimal relationship between the trackwidth and the servo bandwidth of a magnetic disk drive which minimizes the limit signal S/N ratio is proposed which takes into account position signal noise and mechanical vibrations. The idea of required accuracy distribution is introduced. A dual-stage actuator with a single-input single-output (SISO) system is used to confirm the calculated results. This paper describes a method for obtaining the desired servo signal quality and introduces a relationship between trackwidth and servo performance that can make it possible to design head positioning systems for trackwidths under one micron.
