ABSTRACT:
A computer disk drive unit includes a housing having a lower base and an upper removable cover which define a disk storage compartment therebetween. A shaft fixed to the lower base supports a plurality of memory storage disks for rotation within the disk storage compartment. An elastomeric snubber extends between an upper end of the shaft and the upper housing cover, for preventing direct contact and absorbing vibration between the shaft and the upper housing cover. The snubber is a cylindrical member having a lower solid section disposed within a recess in the upper end of the shaft, and an upper tubular section which is compressed as the upper housing cover is secured to the lower base. The upper housing cover includes a thickened portion whereat the upper tubular section of the snubber contacts the cover.
