DVD+RW Alliance: DVD+RW DL (double-layer) products to reveal this year
The DVD+RW Alliance announced at CES the establishment of the "DVD+RW DL" format. The new format features dual layer recording (8.5GB) on DVD.
The recording speed for dual layer recording is not expected to reach the 8x used for single layer DVD+R, due to the high power requirements for dual layer recording. The 2.4x is the debut speed for dual recording, expected to reach the 4X in one year. Initial media will be write-once, while 8cm discs are also included in the specifications, offering 2.66GB available space per layer.
