    Very interesting (and cool). Are there any technical details on how this is exactly done?

    This is obviously high voltage AC. Judging by the arc gap, it's at least 15 thousand volts. Lots of current so there must be a 20-30 pound transformer.
    Doesn't say what type of disk is being erased. The gray color suggest it is an RW type. I don't think it would work with +-R disks as they have no conductive material on them.
    One drawback would be the toxic fumes given off from a RW disk. The phase change layer consists of Indium, Silver, Tellurium, and Antimony. While not immediately lethal, Antimony is almost as toxic as Arsenic, and Tellurium is considered mildly toxic.

    Dunno, a couple of seconds in a microwave erases it pretty thoroughly with random artistic artifacts. :D :cool:

    That wouldn't be cool of course.

    -It would be much faster though...:D
    -It would be more Energy Efficient, too. (No Electricity wasted at all.) ;)
    Besides, the purpose was to ruin CD/DVD’s permanently ...

    The caption under the video reads:
    "Every office should have one of these next to the shredder"
    Most office shredders have no problem shredding disks since they were made to eat staples and even paper clips.
    I have shredded many confidential disks this way. At least I always thought it was fun to chop up disks in the shredder!
