A Study on Dynamic Performance Improvement of HDD Disk-Spindle System
HDD 디스크-스핀들 시스템의 동특성 개선에 관한 연구
Abstract
This paper investigated the dynamic performance of HDD disk-spindle system to reduce disk fluttering. Rocking frequencies of the disk-spindle system and radial NRRO are measured to escape the ball defect frequencies and to determine the relative optimal position of the disk in the motor. It was found that disk fluttering was reduced by increasing disk thickness, inserting viscoelastic material between the disk and the spacer and decreasing the gap between the disk and the base.
