Explains the principles of operation of the Digital Versatile Disc (DVD) Recordable (DVD-R) technology and its principle applications. Explains that DVD-R is able to hold up to 3.95GB of information on each side of a disc to give up to 7.9GB in total using a write-once only technology that is similar in concept to Compact Disc Recordable (CD-R) but with essential technical differences to get the higher capacity and higher data rate of 11.08 megabits per second. Provides details of the makeup of the disc and the two methods of writing; the disc at once method where the complete disc is written at one time from prepared and loaded data, and the incremental method where data can added in small increments until the disc is full. Discusses the use of DVD-R on video players and as a DVD-ROM disc as a versatile device with computer data and not necessarily any video data at all. Describes the use of DVD-R technology for three principle areas: testing the content of DVDs before commitment to mass production; small scale distribution; and storage and archiving. Points out that DVD-R discs can be written on equipment driven from a reasonably powerful computer only and that no exotic components are required.
