Out of these two most popular ones are DVD-R and DVD-RW. Both allow users to record and store media files such as music or movies and run on all devices with DVD drives. The major difference between them lies in the number of times they can be used. Whereas DVD-R is known as readable DVD, DVD-RW is a rewritable DVD. This means that you can store files only once in a DVD-R and cannot erase and record another file on it, DVD-RW allows the user to erase and record information multiple number of times. Amazingly, the quality of modern DVD-RW is such that one can record and reuse them almost a thousand numbers of times.
1 As with DVD-R it can only be recorded on once.  DVD+RW: can record up to 4.7 GB at up to 16Ã speed. Since it is rewritable it can be overwritten several times. It does not need special pre-pits or finalization to be played in a DVD player.
