Disclosed is a Pivot assembly design of Hard Disk Drive. For coil torsion mode improvement, It is desirable that center of two bearings is same level with center of voice motor coil or center of disks. But in thin HDD cases, this is difficult for size restriction. Using appropriate two type bearings, pivot rotation center can be same level as VCM center or disk center, and it is possible to improve coil torsion mode.
