DVD recordable and DVD rewritable are optical disc recording technologies. "R" format DVDs can be written once and read arbitrarily many times. "RW" format DVDs can be erased and rewritten multiple times. Both DVD R and DVD RW come in +/- formats. The essential difference between DVD +/-R and DVD +/-RW remains the same regardless of the + or -. But the DVD +R/RW is suitable for random access and improves compatibility with DVD players.
A DVD RW is cost more and a DVD R, and it takes longer to read and write information on a DVD RW. However, the gap in price between DVD R and DVD RW is getting smaller all the time.
Another difference between DVD R and DVD RW is compatibility. A DVD R drive is an earlier model that is only capable of writing to DVD R discs but not on DVD RW discs. DVD RW drives are backward compatible and are able to read and write to both DVD R and DVD RW discs.
AutoJoy DVD players all support DVD R and DVD RW formats. No matter DVD +/-R or DVD +/-RW.
