Re: [ARSCLIST] Optical disc "repair"

If this sort of machine can buff out the kind of circular or
"horizontal" gouge/scratch that makes a music CD partially unplayable
(ie more errors than can be corrected) or data un-recoverable, than it's
worthwhile to fix those discs and then COPY THE CONTENTS TO A MANAGED
STORAGE SYSTEM AND/OR ANOTHER OPTICAL DISC. As far as using one of these
machines, making the data recoverable/playable and then assuming
"problem solved," well I think that's probably not a the best plan.
Polishing relocates plastic from the adjacent higher areas to fill minor
flaws. Larger scratches are best filled temporarily. Suitable materials
are available commercially which closely approximate the index of
refraction of the polycarbonate. If the original is to be retained, the
fill fluid should be wiped off after copying.
Copying the repaired disc is, as Tom says, the next step and not
optional. Copyright issues are generally secondary in such a case, but YMMV.
