We've all got, or had them, for whatever reason, and recently I found what seems to be a solution to those irritating skips and jumps etc, when the disc seems to the eye, to have no damage at all.
I recently bought a brand new copy of a non soul related CD, and it skipped quite badly on a couple of tracks. I tried a few things to remedy the problem, but with no success, until that is, I used a clean, soft cotton handkerchief and 99.9% Isopropyl Alcohol (those of us with more years behind us, than we have left in front of us, will know it as "rubbing alcohol", and you will most likely have to order it online). It worked perfectly, straight away, and I checked it a day or so later, and it still worked perfectly, and still does today. Obviously, this won't work with screwdriver gouges and the likes of course.
Incidentally, one other remedy, without having to pay out for a new copy, unless the damage is bad, is to use a ROM Drive to copy the disc to a computer, then copy the files back to a clean blank CD. This has worked for me several times times in the past, though why I don't know. Disclaimer: Just to point out, that doing this breaks no laws whatsoever, as long as its for your own personal use.
Sorry if this is in the wrong forum. I'm sure the powers that be, will move it, should it be deemed necessary. Mike
