DVD, technically stand for Digital Versatile Disc, mainly be used for storing video, audio, image, or computer data. There are two DVD type on the market. The 12 cm type is a standard DVD, while the 8 cm variety is known as a mini-DVD.

The following five main terms used to describe the way data is stored on the discs:

Actually, the main difference is the copy right protection. The DVD movies we buy are physically stamped, also contain Macrovision anti-copy protection that prevents them from being copied onto a homemade VHS tape or DVD, while the DVDs we make at home or on PC are optically burned by a laser and generally do not contain the Macrovision anti-copy protection.
