ABSTRACT:
The viscoelastic spacer is made of a layer of viscoelastic material and a layer of wear-resistant, low coefficient of friction material which together form a unitary structure for damping vibration. Spacers are placed at the top and bottom of a storage module containing a disk drive. Upon slidable insertion of the storage module into an enclosure, features on the inner surface of the enclosure engage with the spacer in a way which subjects the spacer to both compression and shear forces generated by vibration of the disk drive and of other vibration sources in the environment of the storage module.
