Has anyone here managed to remove scratches from CDs' (compact
disks) in a lathe?

I have a few that have been abused to the point that I can't copy
them and start over. I have tried various buffing proceedures with
little success. Any thoughts on the feasability of making a backing
plate and taking a light pass or two over the surface.

In WalMart they sell the tool to do the job, it laps the surface
RADIALLY using water to wet the surface and works very well. Ask any
kid near the CD games section and you will learn everything!

A CD-cleaner worked, at least for me. First, it should mentioned that
the label-side of a CD is muct closer to the data than the shiny side.
Damage to the label side is unrepairable.
Damage to the label side (where the label is scratched or worn off - and now
too deeply) can be fixed by applying a marking pen (white would be the
preferred color but anything seems to work). I have rescued quite a few CDs
this way. Hint; Don't put your CSs in the car and drive through an Arizona
sandstorm.

In my case a mechanical failure in the CD player gouged a cut that
looked like a circular Grand Canyon on a software CD that would have
cost real bucks to replace. In a "what can you loose" mood bought
one of these kits and, with lots of elbow grease, polished the groove
out completely. The disk is 100% readable now.
