ABSTRACT:
The present invention provides a method and apparatus to adjust the rotation balance of a disk with high accuracy and ease during manufacturing. A disk is attached to a spindle to form a disk assembly having an adjustable center of gravity. The disk assembly is rotated and thereby generates vibration. A force, which is a function of the vibration, is applied to one or more components of the disk assembly to reduce vibration of the disk assembly below a predetermined value thereby causing the disk assembly to have a second center of gravity.
