Turned out that scratches can easily be avoided if you are careful, and - more importantly - a few scratches won't prevent the disc being read, thanks to the error correction.
Back in the day I remember using one of those AOL internet sign-up junk discs as a drinks coaster, for several years. As you'd expect from grinding around on my desk it was filthy and scratched to total hell, never mind the thermal stress of hundreds of hot tea mugs being sat on it. I'd never seen a CD looking so bad.
One day out of curiosity I decided to wipe it off and put it in the PC to see what would happen. I was genuinely surprised when the AOL splash popped up (and also a little disgusted because I had no love for AOL and was hoping I'd killed it)
A few won't. I have a disc that looks as if it was tested with hot needles many times just for fun.
