Abstract
An improved disk drive spindle hub assembly for a hard disk drive includes a spindle hub, a stack of information storage disks is journaled about the spindle hub in a spaced-apart, vertically aligned relation, annular spacers are positioned between adjacent ones of the information storage disks in order to space the disks apart in the vertically aligned relation of the spindle hub, a disk clamp configured to concentrically clamp the stack of information storage disks in axial alignment with the spindle hub, and a dummy disk formed an arrangement of a metal plate, a damping portion and a polyester film disposed between the disk clamp and the storage disk in order to absorb spurious vibrations and minimize stress concentrations and disk distortion when the storage disks are mounted for rotation within the hard disk drive.
