Microwaved disk to safely destroy data

This guy seems a little crazy. He microwaved (for 5 seconds) a dvd to ensure data can't be retrieved anymore from them. I used to work for a big company which manufactured optical media and I'm inclined to believe that the system can work. As long as the dye, the substance filling the cd/dvd/BD track which is supposed to be figuratively "burnt" by the recorder, is really burnt the information contained in the disk should be similar to the memories of a brain splattered against a wall (ah gore!). I'm no computer forensics but I can't think of any way information can be extracted from such a mush.
Anyway, given that I've never done something like that I don't recommend you to do it because this method surely isn't much healthy neither for the microwave nor for the meal you're going to cook inside it after having burnt a few disks. The dye is meant to evaporate as the compound was originally a liquid made of powder mixed with solvents. Most of the solvents evaporated during the manufacturing process called drying but who knows how much solvent is due to evaporate when you bake the disk inside the microwave?


If you're interested in the process the guy posted a video here.
