I used to work in a lab and a co-worker had be a submarier for the US. He
said that one of their projects was to figure out how to best destroy CDs
for the government. Supposedly the CDs were recoverable even after
cross-shredding. They either decided that melting them over a "heatsink"
(coffee mug) in a microwave (also makes a nice ash tray) or going at them
with an acetaline torch was the final solution.
