Abstract
Herein is disclosed a method and apparatus for coupling a disc to a hub, so as to dampen radial vibrations of the disc. A hub rotates and is coupled to a magnetically encodable disc via a flexible joint. The flexible joint may be made out of a viscoelatic adhesive. There exists no rigid coupling between the disc and the hub, meaning that radial vibrations of the hub result in compression or decompression of the flexible joint, rather than in translation of the disc. The disc may be coupled to the hub by applying a viscoelastic adhesive to a hub, and applying a disc to the viscoelastic adhesive without otherwise rigidly coupling the disc to the hub.
