The shock and vibration absorbing part of the mount is made of elements of molded urethane or similar material that change shape as static loading increases.

As the static load is applied the extra deformation increases the mount stiffness in two ways, there is an increase in load to mount surface contact area and the elements of the mount change from flex loading to shear and compression as the shape of the elements change under load. The natural frequency of the mount in loading is low and relatively constant over a wider range of static loads then prior art mounts.

Abstract: Noise is reduced in a disk drive enclosure by using vibration damping materials on the inside surface of the enclosure. These materials and their placement on the inside surface of the enclosure reduce noise without thermally insulating the disk drive. A temperature controlled fan may be used to remove heat by convection while generating a minimum amount of noise. The connection between the disk drive and the external connector of the disk drive enclosure is made more reliable by using a printed circuit board instead of a cable. Because a printed circuit board has a fixed location and fixed layout, variability among disk drive enclosures can be minimized. Also, errors in manufacturing of the disk drive enclosure can be reduced. To facilitate the use of the disk drive in a stripe set, the disk drive enclosure has a set of mechanical interlocks that permit the enclosures to be stacked vertically.
