The aluminium coating of the CD reacts and creates plasma. So it burns the CD effectively. Below you can see the image of a microwaved CD. It's safe to say it's been destroyed. What Happens When You Microwave CD

It really is a sight to behold, and one worth looking up a YouTube video of. With what happens out of the way, you might ask why it happens. Microwaves (the appliance) produce microwaves (an electromagnetic wave). In their normal application, microwaves are handy because they pass through some materials, like glass, without affecting them, but they create rapid vibration in other materials. These rapid vibrations produce heat as a byproduct, and that heat warms your food. When microwaves touch certain metals, however, an entirely different effect takes place.
