Disk file products currently achieve balancing in various ways, e.g., addition of self-adhesive lead weights, addition of tungsten carbide balls, removal of metal, addition of metal-filled epoxy. All of the above are performed on the spindle hub itself which is a small radius relative to the major out-of-balance force of the disks themselves.
