What is the physical size of a DVD-Audio disc?
The standard size is 120 mm, the same width as a compact disc or DVD-Video disc. As with compact discs, 3-inch (80 mm) DVD-Audio discs can be used. The 80 mm disc format is perfect for artist singles or audio samplers, either for sale or as promotional items. Every DVD-Audio player has the capability to load and play either disc.
