Effective Optical Disc Repair?
CyberKnet writes "I have an extensive music collection on original CD media. While most of it is in impeccable condition, I have a few discs that have suffered extensive scratching through listening to the disc either via a portable disc player, or in a car CD stacker. I've long since learned the error of my old ways and don't listen to discs in those devices any more, but those discs are irreplaceable in many cases. I would very much like to be able to repair them or have them repaired to original condition, or at least well enough that I can pull the tracks off once and archive the track data. I have heard really uncomplimentary things about devices like the Skip Doctor; ranging from it not helping to it making things worse. I've heard great things about JFJ devices that are seen on the counters of most Hollywood and BlockBuster video stores, but even their consumer devices start at $250. I would appreciate any other suggestions for devices that people have had personal experience with that won't break the bank."
Get toothpaste. NOT GEL, but regular white paste. Get a small cloth, put a dab on it, then rub it from the center to the outside in straight lines going outwards around the whole disk. When you're done, clean it off and pat it dry. Disk will look like hell, but it'll work.
I have rescued lord knows how many CDs with this technique, including console ones that were completely screwed, and even resurrected a dead DVD-RW just this past weekend using this technique.
Make a few quick, gentle passes over the recorded side(s) with a common butane blow torch, of the plumbing variety. The heat slightly melts the polycarbonate plastic, causing most scratches to get filled in, and other sharp edges to be smoothed & making reading easier. Tips: 1) don't overdo it, or the plastic might warp, 2) doesn't work well with recorded media (CD-Rs), 3) first practice a couple of times with media you don't mind losing.
