Low-cost and Low-Profile Hard Disk Assemble Structure

      Disclosed is a Hard Disk Assembly (HDA) structure to achieve
low cost by using a base plate by stamping without loosing the
rigidity.

      Hard disk assembly is required to be assembled at low cost.
Generally, stamping parts can be acquired cheaper than casting parts.
Conventionally, a base plate used in a HDA is required to be rigid
for the stability in the servo control and so on.  Then the base
plate is usually got by casting.

      This new structure is consisted from three components which are
shown in the Figure.  The Base is formed from two parts.  One is a
base plate and the other is a shroud.

      The stamped plate is used as a base plate and also as a top
cover, then low-cost can be achieved.  The shroud can be made with
plastic mold or Aluminum extrusion method.

      Base rigidity can be maintained by the shroud, then the
thickness of the top cover and the base can be thin.  This is helpful
to design a low-profile HDA.

      The top cover and the base plate can be utilized for different
height HDAs by changing the height of the shroud.
