the first-selected drive “handing over” to the other when its

disc becomes full. As the disc in the other drive approaches

all being observed correctly as if the third disc was in the first

machine. At the end of the third disc, recording passes to the

other drive of the second machine.

This process will continue until the system runs out of machines

and/or blank discs, or is stopped by the operator. At the end of

the second disc in the last machine, the system will look at the

first drive in the first machine. If this has been reloaded with a

blank disc, the recording will continue in that drive. If not, the

recording will end.
