Abstract
A hard disk drive is damped in order to reduce tracking errors by isolating the drive from the enclosure it is mounted in using one or more pieces of adhesive viscoelastic material. The hard disk drive is mounted by means of a secondary mounting plate having ventilation holes. Vibrations introduced into the drive from the enclosure, as well as rotational vibrations introduced by the rotation of the drive itself, are substantially damped by the viscoelastic material. As a result, tracking errors are substantially reduced.
