DVD-R Recordable

Recordable DVDs are available in two basic formats. The DVD-R is recordable only once, utilizing WORM (Write Once, Read Many) technology to burn data onto the surface of the disc using high-powered lasers. More versatile, yet more expensive, is the DVD-RW format, which is recordable many times over. Through simple interfaces, users can enter commands into the computer system or data duplication unit that orders it to wipe the disc clean of all data stored on it so it can be used again.

Basic Options for Recordable DVD Formats

The most obvious application of the RW format is that it permits for the large-scale transfer of data from one machine to another. Since the average recordable DVD can hold 4.7 gigabytes of data, users can efficiently import data files, erase the disc and fill it again, repeating the process over and over as many times as necessary.

However, the R format is more viable when distributing copyrighted material, since it has read-only protection and guarantees that the disc cannot be reused for any other purposes. The cost of recordable DVDs has come down sharply in recent years, and is expected to fall even further as the data-dense Blu-ray format is poised to become the standard. Thus, consumers with moderate media storage needs have a very cost-effective way to save or distribute data.
