DVD-RW Media

A blank rewritable DVD-RW is a DVD rewritable disc that is much like a DVD-R recordable disc in that it has the same capacity of 4.7GB per disc. DVD-RWs can be rewritten to around 1,000 times before they need to be replaced. This makes them a great choice for less important data like daily TV recordings. Its competitor, DVD+RW has the same capabilities. Many DVD burners and drives can handle both types of rewritable media.

DVD-RW and DVD+RW are competing blank rewritable formats supported respectively by the DVD Forum and DVD+RW Alliance. Hybrid DVD drives that can handle both are labeled DVD±RW. Because there isn't an agreed standard for recordable DVDs, hybrid drives are very popular for their cross compatibilites. Most modern DVD burners are hybrid drives. The + and - of DVD R media are racing to find new innovations to outpace each other. While new upgrades and advancements will ultimately benefit the consumer, you should double check to ensure the DVD Player you purchase can handle both these formats.
