i love the way the disks stick to the towel after falling off
Hold on, Photonicinduction is back?
[QUOTE=Sam Za Nemesis;37316227]Hold on, Photonicinduction is back?[/QUOTE] You bet. Came back as photonvids. I know the video I posted is old but I think a lot of people don't ever see these.
Can't you just snap it in half? Or is that retrievable somehow? [editline]19th August 2012[/editline] Whoa that's cool how you can just watch the data being erased.
The DVD's reaction was quite different than the CD's, interesting.
I'm still watching the video but are they reusable if you erase them that way?
[QUOTE=l l;37316383]I'm still watching the video but are they reusable if you erase them that way?[/QUOTE] Not at all, the data is encoded in the reflective/metallic layer on top. The transparent plastic is merely something to hold that layer fixed so it can be read like a record. That's why a(n) (even heavily) scratched disk is easily fixed, if you just manage to restore the plastic to a state where the laser can still read (i.e. have a light beam transmit the plastic, reflect on the metallic layer and back into a sensor) the metallic layer in an undisturbed manner (by using some sort of gel/material that has a similar refractive index as the plastic).
[QUOTE=l l;37316383]I'm still watching the video but are they reusable if you erase them that way?[/QUOTE] I wouldn't think so as it's burning the layer that the data is written on, off of the plastic disk.
older than cd's themselves

Photon kinda disappeared because of his popularity. Looks like we might have the same thing all over again.

[QUOTE=Ninja Duck;37318007]Not useful at all, destruction of evidence is a crime.[/QUOTE] Between destroying evidence and (maybe) child porn possession, which one would you choose? :v:

I'm sorry but I can't believe that all those cheesy electricity effects in B movies actually look like that my mind hurts.
He reminds me of a young mad scientist richard hammond. This is awesome by the way, I love people who do this sort of thing.
[QUOTE=latin_geek;37316381]The DVD's reaction was quite different than the CD's, interesting.[/QUOTE] My guess is, that it's not as much the difference between a CD and DVD but the difference between a burnable CD and a normally pressed DVD.
[QUOTE=Ninja Duck;37318007]Not useful at all, destruction of evidence is a crime.[/QUOTE] One would assume that they have to prove it was evidence to begin with. They can't just say "what he destroyed was evidence". Maybe it's just a hobby of his and they came knocking at his door while he happened to be vaporizing some CDs for the fun of it. This video is evidence in itself of the possible scenario.
