DVDs are run using 650 nm wavelength light, which is smaller than the type the CD-ROM uses. This allows for finer grooves to be made into the disc, meaning more information can be stored. Early DVDs had a write speed of slightly over a megabyte per minute, while the most more recent models can be over twenty times quicker.
