At 1.2 millimeters, DVDs are the same thickness as CDs, with the main difference being that DVDs are made up of two 0.6 millimeter substrates bonded together.
This allows for a greater rigidity in DVDs over CDs, meaning less 'wobble' occurs when they are spinning and as a result greater reliability for the laser reading. DVDs are available in four component 'flavours' which can be combined in any number of ways to produce your final product.
Each configuration has a different designation, which roughly equates to the storage available. |

DVD-9 is the official designation for a Single-Sided, Dual-Layered 12 cm DVD. DVD-9 has a total storage of 7.95 Gigabytes, which equates to an average run time of 240 minutes.
As a single-sided disc, a number of print options are available for the blank 'label' side.
DVD-9 has become the de-facto standard for most commercial DVDs as it offers enough storage for content producers to provide a large amount of video and audio without compromising the quality of their final product.
