DVDs are LESS resilient because the data is more tightly packed and most DVDs have a dual-layer optical structure. It's far less tolerant of surface imperfections. On badly scratched CDs I use a cheapo disc repair kit (the one I use costs $6.99 and does 20-30 CDs). Think of it like a Zamboni machine - it actually resurfaces the disc. Damage from scratches is really areas on the disc where the laser can't penetrate through to the reflective layer due to scratched grooves on the disc that create reflective surfaces or roughed-up areas that make the polycarbonate too opaque. The kit I use contains buffing compound, buffing cloths and fine (1200 grit?) wet/dry sandpaper. For scratches large enough to cause read errors in EAC I always use the sandpaper. You then finish that up with the buffing compound. Works every time - there's always a reduction in errors although sometimes I have to go over the disc a few times. The only drawback is the massive force you have to use to get the rubbing compound to work. I can only do one or two disc repairs a day before my arm gets too sore. I'm not going to rip into Heuer over the merits of felt-tipped pens and magical sprays in improving discs as he told me not to shoot the messenger, but I will say that the coating is likely filling in scratches. To use an ice analogy again, it's like flooding the ice. The key is this statement: > It should not have to be treated again unless the disc is cleaned with > water surfactant or isopropyl alcohol. So it's leaving a coating that is likely filling scratches in. It could also be that applying the coating just cleans the disc, which works wonders as well. -- Mark Lanctot ------------------------------------------------------------------------ Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=27024 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
