A cd exploded in our cdrom!

My father was ripping some music when it suddenly just stopped working, and out came this:

Is that the new copy-protection or what?!

Haven't you seen Myth Busters, Episode 2, CD-ROM Shattering?

They didn't manage to crack a CD until they switched to a drill engine.

you can do it yourself! Normally when a cd i burned doesnt work i throw it (outside of course). Sometimes you can manage to hit right on the edge then the cd splinters to small pieces! Really cool

And sometimes when you throw them down and hit the edge just right, the bounce.

And sometimes they decapitate.

If you throw the Aussie ones, they come back.

I had this happen once with a CD of a game I had bought in the store that required the CD to be in the drive when you play the game. It can happen with cheap grade CDs or sometimes a speck of dust, but it literally shattered in a million pieces. I had to buy a new CD drive. Literally the CD gets overheated by the laser and falls apart (explodes) on a molecular level.

overheated???? hahaha

Robert Resovich, application engineering manager at drive maker Plextor, says that a CD's generally vulnerable inner ring becomes more so when the disc is spun in the newest drives (currently the standard is 48X/24X/48X). "You get upwards of 10,000 rpm, and at the outer edge, that's roughly the equivalent of 150 miles an hour," he explains. "At that speed, things can come apart."

nothing to do with heat at all..

it is resonance that causes them to shatter.... heat indeed HAHAHAHAHAHA

Yeah its resonance. The laser CAN NOT cut in your skin, and i doubt it really produces much heat.

i doubt it really produces much heat.

You can think what you want, but it doesn't change the facts, nor does it change the fundamental laws of physics.

It is also a common problem with DVD players and trying to play cheap grade DVDRs or VCDs in them. Here in the US, DVD players now carry warnings about the issue.

Burn a cd and then put your hand on it, it can get quite hot!!
