Abstract: A hard disk drive includes at least one magnetic disk and a motor assembly. The motor assembly is configured to rotatably support the magnetic disk(s) and circumferentially rotate the magnetic disk(s) about an axis of rotation during operations of the hard disk drive. The motor assembly includes at least one rotational balancing spring pin. Each rotational balancing spring pin is configured to reduce a rotating unbalance of the motor assembly.
