Abstract
An assembly that couples a spindle shaft to the cover of a hard disk drive. The disk drive has a cover that is attached to a baseplate. Extending from the baseplate is a spindle shaft which supports a hub and the magnetic disk of the drive unit. The spindle shaft has a plurality of protrusions which are embedded into a metal shim. The metal shim is coupled to the cover by a sheet of elastomeric material. The metal shim and elastomeric sheet secure the end of the spindle shaft to the cover of the assembly.
