A DVD-R is a write-once format: once youâve burned the data onto that DVD platter, the disk is forever frozen with that information. Add the âWâ to that, and youâll find that DVD-RW can be erased or rewritten up to a thousand times.
The main difference between DVD-R and DVD-RW, or DVD+R and DVD+RW is that the R disc formats can only be written to once, and then it is only readable and canât be erased for the rest of its digital life. While RW discs are can be written to and erased many times, they are both readable and writeable.
