ABSTRACT:
A disk drive support system suspends a disk drive within a sleeve-like support housing from two upper corners and two lower corners using four parallelepiped shaped elastomeric mounts, one bridging the drive and housing at each corner. Each mount has one zone affixed to the drive and another opposite zone affixed to the housing by tangs on the drive and housing which engage two respective slots in the mount. A third slot is formed in the mount between the two zones so that there is no straight line path between the zones through the material of the mount which is not interrupted by the slot. The third slot thereby prevents transmission of direct compressive forces between the two zones, and thus requires at least some component of force acting between the two zones to act in shear. Shock absorber pads are provided on the disk drive which are separated from the housing by an air space so as to absorb shocks but not transmit vibrations. The housing may be fixed to a printed circuit board which is oriented vertically. The two upper elastomeric mounts are of a higher durometer hardness than the two lower elastomeric mounts.
