See our selection of CD / DVD burners. A CD burner is a device that can record data on a CD. CD-RW (CD-RW) and CD-RW (CD-RW) are the two most common types of drives that can write CDs, either once (in the case of CD-R) or repeatedly (in the case of of CD-RW). In the recording, the data is actually etched into the disc (burned) with a laser, compared to non-recordable CDs. Audio CDs and CD-ROMs are squeezed from copies of original recordings (which are burnt by lasers).
