Abstract

Described is method to provide a removable media tray that can accommodate several types of devices without requiring new tooling for the container. The front of the tray allows use of full-high and 1/2-high devices to protrude for access to the media or be enclosed for a Direct Access Storage Device (DASD). The cover has necessary venting for cooling and the rear of the tray provides mounting for a fan, if required. The inside of the cover and tray base allow for the different kinds and locations of devices and for automatic docking of signal and power connectors. A special grounding tab is designed to provide assurance that a ground connection is made prior to connecting the power lines or the signal lines when the tray assembly is inserted into the slot of the system.

Removable Tray Assembly

      Described is method to provide a removable media tray
that can accommodate several types of devices without requiring new
tooling for the container.  The front of the tray allows use of
full-high and 1/2-high devices to protrude for access to the media or
be enclosed for a Direct Access Storage Device (DASD).  The cover has
necessary venting for cooling and the rear of the tray provides
mounting for a fan, if required.  The inside of the cover and tray
base allow for the different kinds and locations of devices and for
automatic docking of signal and power connectors.  A special
grounding tab is designed to provide assurance that a ground
connection is made prior to connecting the power lines or the signal
lines when the tray assembly is inserted into the slot of the system.

      The cover (Figs. 1-5) is designed with three distinct areas
that can be modified easily in the molding tool.  The tool has
removable inserts that allow the front and rear areas to be changed
for the different devices to be used. This significantly reduces
tooling costs for the revised covers.

      The cover (Fig. 5) has a decorative relief at the front to
allow the draft to match the flat area.  The rear area has a step
down to provide the place for the draft to match. The cover tool is
textured for appearance purposes.  Four tabs are provided for a snap
action fit between the cover and the base.  Projections at the bottom
edges of the base (Fig. 6) provide retention of the cover sides and
the overlap will also give better electromagnetic shielding if coated
or metal- filled plastic is used in the molding process.

      The base (Fig. 6) is designed with auto-latching device to
retain the assembly in the system frame.  The handle is designed for
ease of use and it contains a label recess for device identification.
Projections are provided to retain a fan.

      Fig. 1 is a front view of a tray with a 5 1/4" form
factor 1/2- high tape device installed.  It shows a support bracket
for mounting the 5 1/4" form factor 1/2-high device. The bracket
supports the device along with the power regulator.  A special shield
is shown for electrostatic discharge protection.  The springs o...
