DVD
DVDs (digital versatile
disk) are another popular optical disc storage media format. The main uses for
DVDs are video and data storage. Most DVDs are of the same dimensions as
compact discs. Just like CDs there are many different variations. DVD-ROM has
data which can only be read and not written. DVD-R and DVD+R can be written
once and then function as a DVD-ROM. DVD-RAM, DVD-RW, or DVD+RW hold data that
can be erased and re-written multiple times. DVD-Video and DVD-Audio discs
respectively refer to properly formatted and structured video and audio
content. The devices that use DVDs are very similar to the devices that use
CDs. There is a DVD-ROM drive as well as a DVD writer that work the same way as
a CD-ROM drive and CD writer. There is also a DVD-RAM drive that reads and
writes to the DVD-RAM variation of DVD.
