Conformal Base Design for Type II Personal Computer Memory Card International
Association Direct Access Storage Device Design

      A base design for Type II Personal Computer Memory Card
International Association (PCMCIA) Direct Access Storage Device
(DASD) that allows for placement of the electronics card on the
outside of the file and still provide an acceptable structural design
is disclosed.

      Type II PCMCIA DASD has a very limited height in which to
package both the electronics and the mechanics of the disk drive.
Due to this limitation, the effective use of the height is very
critical.  The design concept disclosed is used to put the
electronics on the outside of the disk enclosure, as opposed to
placing the electronics on the inside of the disk enclosure.  The
design concept involves designing the base to "conform" to the
electronics layout.

      The Figure shows what is essentially a "reverse-image" of the
electronics package (1) on the base (2).  The electronics package is
then able to occupy all the space that is not used by the base when
the two pieces are mated together.  This design allows for
significant amounts of base material, while still allowing the
electronics to use a maximum amount of room.

      Implementation of this design is best accomplished by
completing the design of the base after the electronics package is
defined.
