            Know More about DVD Media

Original DVDs (Digital Versatile Discs) typically store up to 4.7GB of data or more than 6 times the maximum storage of 700MB for a CD disk.

DVDs store digital data in microscopic grooves running in a spiral around the discs. Data storage tracks are smaller than on CDs so more data can be written on the same physical disc. DVDs require special laser beams to scan and read the data stored on these smaller tracks.

DVD-R and DVD+R (Recordable) are optical discs that can be written once and cannot be erased. Recordable DVD discs are often used for long term data storage and archiving.

DVD-RW and DVD+RW (Rewritable) are optical discs that can be erased and can be rewritten. DVD-RAM is also a rewritable standard media. Rewritable DVDs are often used for general storage and backup applications.

No single standard exists for recordable DVDs and there are significant technical differences between the two standards. The DVD-R format is supported by the DVD Forum while the DVD+R is supported by the DVD+RW Alliance. New dual standard drives that can handle both formats are often labeled DVD±RW and are very popular.

Dual Layer recording increases the capacity of DVD-R and DVD+R discs to up to 8.5 GB per disc and store significantly more data on a single disc. Manufacturers started incorporated Dual Layer technology into commercial DVD drives in mid-2004. DVD recordable discs supporting this technology are backward compatible with most existing DVD players and DVD-ROM drives.
