A digital video disc DVD , also known as a digital versatile disc , is an optical disc that stores data and video.

Optical discs are circular discs that are read and translated by lasers. There are several types and formats, but most DVDs fall into one of three main categories: read-only, writable, and erasable. It is important to understand the difference between the formats because they are not interchangeable, and each type will only be compatible with specific disc drives.

Read-only memory discs are the type of discs that are purchased with media already on them. Movie discs fall under this category. The data and videos on these discs cannot be erased and no data can be added, therefore they are referred to as a non-writable DVD. The first type of writable DVD was called a random access memory RAM disc, but these are no longer compatible with most computers. Now, most computers with writable, or recordable, drives require a DVD-R. This type of disc allows the user to record, or write, information to the DVD.

The entire disc must be deleted before the user can add new data or media. This adds more capacity. When selecting a DVD format, one should first check to see which formats are compatible with the disc drive intended for use with the DVD.
