I believe the archival quality of cd in any environment has yet to be standardized, but in my opinion you should be worried about scratches (as Timothy noted), among other things. There is a wiki* on fixing damage, including an important note that damage from scratches to the very thin label side will ruin the data. The reflective aluminum layer inside the disc can also be degraded through temp/humidity fluctuations, especially older CDs**. In the wiki you can see that fungal spores have grown on discs that are in direct contact with cardboard based containers, so I would avoid prolonged direct contact if at all possible. Even the edge of the disc is vulnerable it seems *** Empty spindles seem like a good idea, but raises the question label to label or label to shiny. I used to worry that the label side would have debris that would scratch the read side when stacking discs, but after reading the wiki you can see that it's actually the opposite one should be concerned about. Cleaning both sides before stacking would help a lot. The safest solution would be to keep the discs in standard jewel cases (substituting a regular plastic case if they came in cardboard), stored vertically to avoid warping, in a temperature/humidity controlled environment. A CD cave. An added benefit would be that you could put just the liner notes in a fancy photo album rather than a cd wallet. OTOH if you insert/remove to play them a lot, the flexing from a tight gripping center support can delaminate the aluminum layer which may lead to deterioration as well [source needed]. Some Mobile Fidelity Sound Labs gold discs have a convienint lift mechanism to combat this, so if you buy only MFSL you should be all set... This thread is a lot like the backup thread, in that you can take it as far as you see fit. * http://wiki.slimdevices.com/index.cgi?DiscRepair ** http://www.usatoday.com/tech/news/2004-05-05-disc-rot_x.htm *** http://www.itl.nist.gov/div895/carefordisc/CDandDVDCareandHandlingGuide.pdf (p.11 section 3.4) -- Skunk ------------------------------------------------------------------------ Skunk's Profile: http://forums.slimdevices.com/member.php?userid=2685 View this thread: http://forums.slimdevices.com/showthread.php?t=33418 _______________________________________________ ripping mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/ripping
