Dual layer refers to a
DVD recording technology that provides users with 8.5GB
of recording space (as opposed to 4.7GB of space) on a standard
DVD+R discs). The additional recording space is the direct result of dual
layer technology. As the name suggests, dual layer technology provides two
individual recordable layers on a single sided DVD
disc. To take advantage of dual layer technology when recording DVDs, you
must use a dual layer enabled DVD burner and dual layer DVD media. Dual layer
technology media can be read (once recorded) by most DVD drives and players
currently on the market. Dual layer technology has been used for many years in
the production of commercial DVD movies but is now available for home and
business recording as well.
Dual Layer is more commonly called Double Layer in the consumer market, and
can be seen written as DVD+R DL or DVD-R DL on recordable DVD media and hardware
packaging.
