Verbatim rewritable discs can be written and rewritten over and over again. SERL technology allows continual rewrites without the loss of quality or sound degradation.
These 8cm Rewritable DVDs have a capacity of 1.4GB or 30 minutes of recording time, and although smaller in diameter than regular DVDs, still work well in most DVD players. They can be rewritten up to 1000 times with no loss in quality. The +RW media has the added benefit of not needing finalisation, just record and playback and continue recording.
