Abstract
A hard disk pack assembly is attached to a motor powered rotatable member in a disk drive by a spring ring. A disk hub mounts one or more disks, functioning as an axial disk spacer when more than one disk is installed. The disk hub has a central circular opening fitted about a cylindrical body on the rotatable member and seats upon a shoulder on the cylindrical body. A spring ring snaps radially inwardly into a circumferential groove in the cylindrical body in a position wedged between surface of the circumferential groove and an upper circular edge of the circular opening in the disk hub to apply axial and radial components of spring force to the disk hub for the purpose of securely seating the disk hub on the shoulder of the cylindrical body and to center the disk hub with respect to the cylindrical body.
