Abstract

A disk drive includes a pivot-bearing cartridge configured to pivotally support the head stack assembly on the base of the drive. A tolerance ring is coupled to the pivot-bearing cartridge and includes a single sleeve defining an inner sleeve surface facing the pivot-bearing cartridge and an outer sleeve surface facing away therefrom, and a layer of dampening material disposed on the inner or outer sleeve surfaces so as to be in contact with the pivot-bearing cartridge or the bore surface of the through bore that is defined in the body portion of the head stack assembly, respectively.
