| DVD-RW (Digital Versatile Disk Rewritable) is very similar to a DVD-R except the data on it can be wiped in order for it to be written on again. DVD-RW area good choice to use to backup data and they are capable of holding 4.7GB, however they are not double sided and in order to write anything to a DVD-RW you must have a burner that supports DVD-RW. |
