detailed:Description:
Dual-layer DVD-R technology provides the ability to record up to 8.5 GB of data on a single disc surface. This nearly doubles the standard DVD capacity of 4.7 GB. That means one side of a DVD-R disc will hold up to four hours of DVD quality video or 16 hours of VHS quality video. Dual-layer discs can also be read on DVD players that were originally designed for single-layer discs. In addition to its dual-layer DVD-R capabilities, this drive allows you to read and write to CD-R, CD-RW, DVD-R, DVD-RW, and DVD-RAM discs.
