Whereas DVDs hold up to 2 layers per side, standard VMDs can use 4 layers, for 20 GB of storage. There are also reports of 8- and 10-layered versions which can hold 40 and 50 GB, respectively. DVD (commonly known as Digital Versatile Disc or Digital Video Disc) is an optical disc storage media format that can be used for data storage, including movies with high video and sound quality. ...
