DVD

DVD stands for Digital Versatile Disc. It was originally referred to as Digital Video Disc.

The purpose of developing DVDs was to create a medium which could hold significantly more data than a CD-ROM. You can store two layers of data on each side of a DVD. The first layer can hold 4.7 GB and the second layer 3.8 GB, which means that a single-sided DVD can store 8.5 GB of data. DVDs can only be read by DVD drives, which can also read CD-ROMs. Unfortunately many DVD drives are not able to read CD-Rs. Even fewer can read CD-RWs.

Currently the following types of DVD are available:
