Abstract

A criterion for the selection of spindle motor speeds in a hard disk drive (HDD) is investigated to guarantee stability and reduce nonrepeatable runout of a spining disk. Since the natural frequencies of the spining disk and the forced frequencies generated from the spindle motor depend on the rotating speed, careful consideration should be taken to avoid the resonance between the disk and motor. To do this, the natural frequencies of the spining disk are calculated and they are compared with the forced frequencies from the spindle motor.
