DVD-ROM

DVD-ROM is the term used to describe any digital versatile disc (DVD) that is read-only. The use of the term in general is often reserved for retail DVD "pressed" discs or specifically, DVD Data discs (excluding those with DVD-Video compilations stored). This usage is actually incorrect as DVD-ROM can be used to describe literally "any" DVD disc that cannot be written to. This also applies to a burned DVD-R and so is not only reserved for pressed media.
