DVD
A technology that uses five inch discs similar to CD-ROMs but which can hold much more data. A DVD disc can deliver multi-channel sound and TV images three times sharper than videotape. DVD players, expected to debut in late 1996, will be interoperable with televisions, stereos, personal computers and some video games. Unlike CDs, DVDs can hold data on both sides and can provide either one or two layers of data on each side. A single-sided single layer DVD holds 4.7 gigabytes of data while a double-sided double-layer DVD holds 17 gigabytes.
