Reduction of Flow Induced Vibration in HDD
It is our purpose to clear mechanisms of Flow Induced Vibration (FIV) on Hard Disk Drive (HDD) and to propose way to reduce it.
The flow between rapidly-rotating disks is to become turbulence, pressure fluctuation upper and lower sides of a disk is increased. It contributes to the problem of positioning error between magnetic head and recording disk and associated track misregistration due to FIV.
In the current study, we pay attention to asymmetric vortical structure in the outer disk region and examine how interaction of structures influences disk FIV.
