CD rewritable simulation CD-RW's characteristics. CD-R works as a Write/Read Many storage. When data is written, physical marks are made on the media surface by a high-powered laser. Then, it can be read out many times just like the usual CD-ROM disks with a normal low read power. When is heated with the middle-powered laser, the recording layer can be converted back to the initial state. So, it's erasable too, java applet

Compact disc this tutorial explores how a laser beam is focused onto the surface of a spinning compact disc, and how variations between pits and lands on the disc surface affect how light is either scattered by the disc surface or reflected back into a detector, Educypedia : java applet
