Capacity of DVD

The DVD specifications emphasize the 12cm disc, which involves single and dual-layer, as well as single and double- sided discs, as shown in the following chart. The generic designations are: DVD-5, DVD-9, DVD-10 and DVD-18. DVD-R is implemented with a capacity of 3.95GB, and DVD-RAM with a capacity of 2.66GB--although now DVD-R’s are 4.7 GB and DVD-RAM’s match that in Type II. Incidentally, we should also note that the DVD specifications include the much-less common 8cm format, with the same layer and side options of the 12cm disc--their corresponding capacities are shown below. The playing time of a DVD Video depends on the average video stream, which depends on the quality of video and audio output. An average video stream of 4.7 Mbits/sec leads to 133 minutes playing time per single layer--a figure often used to mean much more than that.

New media coming out now has dual layer (8.4 GB of storage capacity)… however it should be noted that this is brand new and will not work on a majority of set-top DVD players.
