Abstract
A method of balancing a disk pack for use in a disk drive according to an aspect of the present invention. The disk pack includes a spindle motor and a rotatable disk. The spindle motor is configured to rotate the disk about an axis of rotation of the spindle motor. The spindle motor has a spindle motor imbalance location indicia upon the spindle motor indicative of a location of a spindle motor location imbalance. The method includes detecting the spindle motor imbalance location indicia. The method further includes placing the disk upon the spindle motor. The method further includes attaching the disk to the spindle motor with the disk being off-set from the axis of rotation based upon the detected spindle motor imbalance location indicia for balancing the disk pack by producing a disk off-set imbalance in relation to the axis of rotation.
