Sony optical drives pwn all

I've known that I can fix a screwed up CD by copying it in my PC for a while. Still, I had some CD's that were so profoundly f'd up, that even that hadn't worked for me. Until now that is. I got a 16dvd/40x CDRW combo drive, and a 52x CD for the new machine. They are the newer short form factor drives, which was very nice when building the machine. I have a CD here that I figured I'd give a try with the newer drives. It actually has a piece of the foil missing in the first track. A patch about .015" wide and .125" long, along with some of the worst scratches I have ever seen. I got it off ebay cause I really like the group, and they are very hard to find, being a foreign band from the 80's.

While the buffers dropped very very low in track 1 where the monster skip was, these sony drive made me a perfect CD. I just listened to the whole thing. No problems.

I'm going through my CD graveyard now.

Nah, metric is the dumbed down version for nubs who need everything in base 10.

The Cross Interleaved Reed-Solomon Code (CIRC for short!) used on audio CDs is actually pretty robust. It can completely correct burst errors of up to 3500 bits, which corresponds to 2.4mm of disc. Beyond that, it can interpolate errors up to 12,000bits, which is about 8.5mm of damaged disc!
