Otherwise it would be possible to wipe them clean with a magnet & use again, wouldn't it. PJ	Poppa John (284)

This can't be re-written or altered in any way without destroying the layer(s) in the process. As for 'home burnt' CD's - these use a dye which actually physically changes in response to the energy of the CD's laser. The change is a 'one-way' process for the basic (write-once) type of CDs. The re-writable varieties have a fancier dye which can be flipped from one phase to another. As for the original post - donating CDs to artists is another option. They can do some very neat stuff with the shiney data side. I'd take care to never 'donate' anything that contains personal data however.	Paul.Cov (425)
