1. Horizontal drive motor
2. Gripper assembly
The vertical and horizontal actuators move the gripper into position to pick and
place tape cartridges. The rotary actuator rotates the gripper 180 degrees, allowing
the gripper to pass cartridges between the front storage bins and the back storage
bins or tape drives. The extension actuator extends the gripper forward to make
contact with the desired cartridge and then retracts the gripper to remove the
cartridge from a bin or drive.
The gripper includes a Class II Laser 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. For example, an inventory occurs automatically
whenever the library is turned on or after the door has been closed. You can also
initiate an inventory manually 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.
