Hard disk drive (HDD) assembly of small form-factor HDD shock-mounted in frame having dimensions of larger form-factor HDD
First Claim
1. A hard-disk-drive (HDD) assembly comprising:
- a frame having exterior dimensions of length L1, width W1 and height H1;
an HDD having an exterior height H2 less than H1;
a pair of mount assemblies paired with and attached to either the sides of the frame or the ends of the frame and supporting the HDD within the frame with the HDD'"'"'s height midplane being substantially coplanar with the frame'"'"'s height midplane, thereby providing a spacing between the HDD'"'"'s exterior height and the frame'"'"'s exterior height, each mount assembly including a cantilever arm with its free end attached to the frame, the mount assemblies permitting movement of the HDD in the direction perpendicular to the plane of the disk and providing relatively high stiffness parallel to the plane of the disk; and
an electrical cable within the interior of the frame and having one end connected to the HDD and the other end exposed to the frame exterior.

Abstract
The invention is a hard-disk-drive (HDD) assembly that includes a flame having the exterior dimensions of a particular form-factor HDD, an HDD with a form-factor smaller than the frame, a pair of mount assemblies that support the HDD entirely within the larger form-factor frame, and an electrical cable located entirely within the frame and having one end connected to the HDD and the other end exposed to the frame exterior at the position determined by the specifications of the larger form-factor. The HDD assembly thus presents a smaller form-factor HDD as a fully plug-compatible alternative to a larger form-factor HDD. The mount assemblies have spring-like cantilever arms in contact with damping material to provide a highly-damped nonlinear spring system that provides mechanical-shock resistance for the HDD in a direction normal to the planes of the disks and high stiffness in a direction parallel to the planes of the disks.

20. A hard-disk-drive (HDD) assembly comprising:
-
a frame having exterior dimensions of length L1, width W1 and height H1; an HDD having an exterior height H2 less than H1; a pair of mount assemblies supporting the HDD within the frame with the HDD'"'"'s height midplane being substantially coplanar with the frame'"'"'s height midplane, the mount assemblies being paired with and attached to either the sides of the frame or the ends of the frame;
each mount assembly having a height no greater than H2 and comprising a cantilever arm extending substantially coplanar with the HDD'"'"'s height midplane and having its fixed end attached to the HDD and its free end attached to the frame, and damping material between the cantilever arm and the frame; andan electrical cable within the interior of the frame and having one end connected to the HDD and the other end exposed to the frame exterior. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
