DVD is an abbreviation of Digital Versatile Disc, the successor to the Compact Disc (CD).

In a nutshell, a 120 mm DVD can store at least 4.3 GiB worth of data, which is far greater than what a 120 mm CD can (up to 0.8 GiB if you're lucky).

DVD's birth process was not a painless one, quite unlike CD's, because there are several companies/groups each pushing their competing technology with obvious vested interests.

Recordable DVD[edit]

Similar to CDs, DVD also comes in recordable (and rewritable) varieties. Unfortunately, there are competing standards for DVD recordable technologies; most modern DVD drives, however, should be able to read these different technologies without much problem.

Future of DVD[edit]

Like its conception, DVD's successor also shows signs of fracture, with competing standards such as HD-DVD, BluRay, and HVD.
