DVD | DVD-R (DVD Recordable

• DVD Recordable (DVD-R) technology allows anyone to create DVD discs at the desktop.

• Similar in concept to
  • Compact Disc Recordable (CD-R), DVD-R is a write-once medium that can contain any type of information normally stored on mass produced DVD discs – video, audio, images, data files, multimedia programs, and so on.
  • Depending on the type of information recorded, DVD-R discs are usable on virtually any compatible DVD playback device, including DVD-ROM drives and DVD Video players.
• A DVD-R disc is able to contain a maximum of either 4.7 or 3.95 billion bytes of information on each side, depending on the type of blank media used.
• Since the DVD format supports double-sided media, up to 9.4Gbytes can be stored on a single double-sided DVD-R disc.
• Data can be written to a disc at a DVD "1X" equivalent of 11.08 megabits per second (Mbps), which is roughly equivalent to nine times the transfer rate of CD-ROM's "1X" speed.
• After recording, DVD-R discs can be read at the same rate as mass-produced replicated discs, depending on the "X" factor of the DVD-ROM drive used.
• These transfer rates, coupled with DVD-R's capacity and conformance to worldwide DVD standards, makes it an extremely viable and cost effective storage medium.
