Ask yourself this: would you try that little trick on a camera lens? There's one trick I can suggest. If the scratch is deep but small, apply a bit of Mop N Glo with a cotton swab. Do NOT apply to the entire surface of the disk. Regard this as a temporary measure, and replace the disc if it's practical. Standard dislaimers apply: it's your backside if you mess anything up as a result of using this suggestion. Fred fbaker@nyx.cs.du.edu >-- Mike Uchima >-- uchima@fnal.fnal.gov
