The Digital Versatile Disc or DVD, with its innovative volume, speed, superiority and convenience is the ultimate in modern technology and is transforming the world of entertainment, media and storage.
The DVD gives exceptional video-image quality and excellent hi-fi sound – it is the perfect data carrier for multimedia applications. A DVD is ten times faster than a CD and can record up to 8 different audio tracks and 32 subtitle tracks.
There are three common formats – DVD-5, DVD-9 and DVD-10- with capacities ranging from 4.7GB to 9.4 GB
DVDs and CDs are identical in appearance, but differ in key physical parameters. The DVD-disc always consists of two substrates (thickness of 0.6mm), which are bonded together. Both substrates can contain information with each substrate having one or two layers of information.
