DVD

DVD is a digital optical disk storage format that was invented and developed by Sony, Toshiba, Phillips, and Panasonic in 1995. It is sometimes referred to as “digital video disk” and/or “digital versatile disk”.

There are three kinds of DVDs. First, the DVD-ROM, which are disks where data can only be read and not written and erased (these are often mass-produced using molding machines that physically stamp data onto the DVD). There are also blank and recordable DVD disks (DVD-R), which can be recorded once by using a DVD recorder and then function as a DVD-ROM. Additionally, there are DVDs that are rewritable, (DVD-RW and DVD-RAM), which can be recorded on and erased multiple times.

Another component is DVD-Video and DVD-Audio the first of which is a consumer digital video format and the latter is consumer digital audio format. Other forms of DVDs hold high definition data and material (AVCHD format) and DVD data disks.
