DVD-R DL. DVD-R DL (DL stands for Dual Layer), also called DVD-R9, is a derivative of the DVD-R format standard. DVD-R DL discs hold 8.5 GB by utilizing two recordable dye layers, each capable of storing a little less than the 4.7 gigabyte (GB) of a single layer disc, almost doubling the total disc capacity.
On the other hand, DVD-RW stands for rewritable DVD that allows a user to erase and reuse it for storage multiple numbers of times. â¢ Reusability option makes DVD-RW more expensive than DVD-R. â¢ DVD-R is available in dual layer format with a storage capacity of 8.5GB which is not the case with DVD-RW.
