Abstract
A disk separator for a disk assembly of a disk drive is provided herein. The disk assembly includes a plurality of storage disks which are spaced apart on a spindle by a plurality of the disk separators. As provided herein, each disk separator includes a disk spacer and a pair of disk dampers. The disk spacer is rigid and includes a first section which extends between adjacent storage disks for maintaining the storage disks accurately spaced apart on the spindle. Each disk damper is positioned between one of the storage disks and a second section of the disk spacer for dampening the level of vibration in the storage disks. The reduced vibration level decreases the level of mis-registration which occurs during operation of the disk drive and allows for the use of high rotational speed, high density, storage disks.
