It really depends on how the cd is produced.
On some of the older CDs I have, I can scratch the hell out of the top of them and not have any problems. Because the reflective material on the inside doesn't depend on a backing.
As BA has said, some of the newer disks produced have a different reflective layer in the middle (probably cheaper to produce) that depends on having a solid backing (the top of the cd).
I have also found that scratches to the tops of these disks can be easily repaired with the application of a bit of indelible marker. (masking tape also works, but that weighs enough to offset the balance of the disk).
I find it much easer to whip out a sharpie and cover any scratches on the top of a CD I own, than buff out the bottom. So I will have to disagree with BA on the safest way to leave a CD lying around.

I think that the vaporization of the metal would have deformed the plastic layers to the point that you can't make out the 100nm pits. So no, it's toast.
