mode, you (or the backup software) can specify which

Sequential
mode supports certain backup applications that do not

the end of the tape, the autoloader automatically returns that cartridge to
its slot and loads the cartridge from the next higher numbered slot to the
tape drive to be read or written to. This continues until the backup
software stops accessing the drive or until all the cartridges have been

is to allow for operating systems that do not support multiple
LUNs.
