VCM Design to Improve Dynamic Performance of Actuator in a Disk Drive
하드 디스크 드라이브 엑추에이터의 동적성능향상을 위한 VCM 설계
Abstract
As high-capacity disk drives pow in track density, the allowable level of PES is becoming smaller. In this paper, some design concept of actuator is introduced to suppress the Butterfly mode that imposes the fundamental limitation on servo bandwidth. The effect of dynamics of proposed actuator on PES is examined by simulation.
