    Uses an electrical arc to damage the top surface of the disc, where the information is stored.

    He used high current to vaporize the aluminum coating on the outside of the CS. Thus, all that`s left is the clear plastic.

    How it works? There is a very thin layer of metal sandwiched in every cd. That is what is conducting the voltage. This a rather final solution.

    "or you could break it in half"

    It`s still partially readable if it`s just broken. If you want to truly destroy the information, this is a nice, quick way to do it.

    How it works: 9v battery is for the motor to spin the CD, CD has conductive layer (where the data is stored) 2 coils get powered up, electricity always follows the path of least resistance, so it starts with the outer layer of the CD, since the surface is more conductive than air or plastic, as it spins, the data layer vapourizes (don`t breathe it!)

    The CD information is actually embedded in the plastic (on production CDs). He is just removing the reflective surface, which, if you really wanted could be reapplied to get all of the CD information.

    The reflective layer on CDs is aluminum (the information is encoded by pinholes in that layer). I assume it is cooking off the aluminum.

    This likely would not work with a writable CD, since the layer isn`t always metal.

    @lazyme: I don`t know specifically, but if law enforcement can recover data from a hard disk that has been melted in a fire, then I`m sure they can get some information off a Disc that has been simply broken in half.

    auburnjunky: Snapped CDs are easy, either just laminate a new disc on the top of the pieces, or take a very high-res photo of the surface and let a computer decode it. If you want tocompletely destroy a CD, you have to melt the plastic layer.

    GasMaskKid: auburn is actually right, even if you format a hard drive, drill holes in the discs and throw it in a fire there are methods of recovering data with surprisingly high accuracy.

    The only way to completely "kill" the information on a hard drive is to either EMP the poo out of it or have a program repeatedly overwrite it with random data.

    TiredofNicks: No, I`m pretty sure if you "drill holes in the disks and throw it in a fire" the data is gone forever. Especially the fire part. If the disks melt, it`s all over.

    Drill holes in a hard disk and the chances of getting data from it are minimal and would require very sophisticated hardware and software as well as technical skill. Snap a CD and again the data is practically irretrievable and no amount of high resolution photos will work as the disk will fragment. With a writeable CD the emulsion will disintegrate and fragment to a point where it is impossible to retrieve data.

    Anyone else remember the broken with Kevin Rose, made a laptop with a Thermite booby trap switch. That`s how you wipe the hard drive so no one can read it at all.

    The easiest way to erase a CD or any other media is to give it to my girlfriend and say `hey, keep this safe`.

    guaranteed the data will be completely lost for good within the day.

    It`s not erasing it, it is removing the aluminum from the inside of it. It is effectively destroying it. This CD isn`t erased, it`s broken.

    If she scratches the hell out of it, give it a good coat of toothpaste, let it dry, then wipe it (gingerly) until it`s all gone. The toothpaste will fill in the scratches and the lazer won`t skip anymore.

    based on how fast it`s working, the heat is gone before it could melt the plastic so lots of cd`s would still be readable if you just re-mirrored it...

    But how would you access the "shiny part" (I don`t know what it`s made of). Thats stuck being two layers of plastic.

    @Canoas I don`t think the shiny surface is sandwiched between layers. We used old CDs as bird scarers, and after just a few weeks the shiny side had flaked off leaving clear plastic discs.

    They use aluminum for the shiny part in the middle. For master recordings, they use 24K gold. I have a copy of Pink Floyd "Dark Side of the Moon" pressed on 24K gold.
