Experimental study of the effect of external disturbances on performance of high density hard disk drives

Abstract

To enhance the performance of the hard disk drives (HDD) and reduce data access time, the track density and spin speed will be increased in next-generation disk drives. However, the increase in track density and high-speed rotation will usually cause problems such as noise and vibration. As such, there is a need to study vibro-acoustic effects on the performance of a HDD.
