Figure 14 CHM (Cartridge
Handling Mechanism)
The vertical and horizontal actuators move the CHM into position to pick
and place tape cartridges. The rotary actuator rotates the CHM 180°,
allowing the CHM to pass cartridges between the side storage slots and
the back storage slots or tape drives. The extension actuator extends the
CHM forward to make contact with the desired cartridge and then
retracts the CHM to remove the cartridge from a slot or drive.
The CHM includes an optical scanner that reads standard six-character
(7 characters for SDLT and 8 characters for LTO), 3 of 9 barcode 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 when the doors have been opened. An inventory can also be
initiated from the host computer.
Although the library does not require tape cartridges to have barcode
labels, properly labeled tape cartridges and full storage slots speed up the
inventory process.
