The vertical and horizontal actuators move the mixed media
gripper into position to pick and place tape cartridges. The rotary
actuator rotates the mixed media gripper 180 degrees, allowing the
mixed media gripper to pass cartridges between the front storage
bins and the back storage bins or tape drives. The extension
actuator extends the mixed media gripper forward to make contact
with the desired cartridge and then retracts the mixed media
gripper to remove the cartridge from a bin or drive.
The mixed media gripper includes a Class II aser bar code scanner
that reads standard six-character, 3 of 9 bar code labels. The
scanner is used to maintain an inventory of the tape cartridges
within the library. An inventory occurs automatically whenever
the library is turned on or after the bulk load door has been closed.
An inventory can also be initiated from the host computer.
Although the library does not require tape cartridges to have bar
code labels, properly labeled tape cartridges and full storage bins
speed up the inventory process.
