disc. However, in no event does TOSHIBA guarantee the operation, 
quality or performance of any disc. Disc quality can affect write or

may occur. Be careful to check the disc for dirt or damage before you 
use it.

a computer drive.

DVD-RAM discs designed without a cartridge. You cannot use a disc
