A host computer communicates with the library through a SCSI 
interface using the SCSI-2 medium changer command set. In a 
typical operation, the robotics receive a command from the host 
computer to transfer a tape cartridge from one FSA component to 
another (storage bin, tape drive, and load port).  To transfer a 
cartridge, a gripping mechanism aligns itself with the designated 
tape cartridge and “picks” it from the FSA component. It then 
moves and aligns itself with the designated location within the 
FSA and “places” the tape cartridge.
