Disk File Mounting Design

      Described is a design for mounting a hard disk file in a
ventilated user equipment cabinet whilst protecting it during use
from mechanical shock, overheating and vibration; also from handling
damage during manufacture.

      The new file assembly is shown in the Figure as an exploded
diagram with an end view of the assembled file.  The Head/Disk
Assembly 1 (HDA) requiring shock protection is mounted on a metal
subframe 2 which has two pairs of shock mounts 3 fitted at the top
and bottom; bottom pair not shown.  The HDA on subframe 2 is then
fitted into an enclosure 4.  A flex assembly 6 carrying electrical
connections from switch 9 to HDA 1 fits between subframe 2 and closed
side 10 of enclosure 4.  Electrical bonding of enclosure 4 to the
external equipment housing is by means of two bare RFI springs 7
threaded on two spring retainers 8.  Side 11 completes the enclosure.
Cooling air is circulated through vents 5 situated at both ends
directed across the HDA in the most efficient path by strategically
placed foam shock and noise absorbing baffles, not shown in diagram.

     A variation to this design is to use the same subframe 2 design
as described above but without shockmounts 3.  The file and subframe
assembly is then simply dropped into a foam pocket within the
enclosure 4 and is trapped in the enclosure when lid 11 is attached
and fastened.  The foam pocket still allows the subframe to move in
all axis whilst maintain...
