Damped disk spacer

摘要

A spacer assembly for a spindle motor of a hard disk drive. The spacer assembly separates a first disk from a second disk of the disk drive. The spacer assembly includes a first layer of damping material located between a washer and a spacer. The first layer of damping material damps vibration that is transmitted through the spacer assembly and into the disk. Damping vibration reduces track mis-registration in the disk drive due to mechanical vibration.
