DVD RW

[Vania]

Stands for Digital Versatile Disk Rewritable. A DVD RW is like a DVD R, but can be erased and rewritten. DVD RWs must be completely erased in order for new data to be added. DVD RW discs can hold 4.7GB of data and do not come in double-sided or double-layer versions like DVD Rs do. Still, 4.7GB of data is a lot of storage space. Combined with their ability to be re-recorded, DVD RWs are a great choice for making frequent backups of your data. To record data onto a DVD RW disc, youll need a DVD burner that supports the DVD RW format.
