Abstract
To minimize unwanted motion in a hard disk assembly in a hard disk drive, an elastomeric support is employed to mount a hard disk pack for rotation by a motor rotor of a disk spindle motor. The hard disk pack includes a hard disk support ring which has opposite annular axial faces upon which the hard disks are securely mounted and axially spaced thereby. An elastomeric connection between the hard disk support ring and a cylindrical body of the motor rotor of the disk spindle motor, provides a soft, or compliant, support for the hard disk pack.
