These CDs are called CD-RWs (Rewritable CDs) and can be recorded/erased again and again. CD-RWs are generally supplied in smaller packs of 10 discs and usually write at slower speeds such as 12x, or 24x. Reuse is simple- simply use your recording software to erase the CD and record again. If you keep your CDs free from dirt and scratches these CDs can be recorded on hundreds of times. As with write-once CD-Rs the recording capacity is usually 80 Minutes or 700MB.
