[SOLVED] would putting CDs in a vacumn prevent disc-rot?

[Deleted member 2707986]

my dad has one of these large air-tight bags for storing clothes, there is a nozzle on the bag that you can attach to the hose tube of the vacuum cleaner, which is then used to suck out all the air in the bag.

if cd-rom discs are stored in an environment where there is no air to cause oxidation/rusting of the aluminum foil on pressed discs, will it help to prevent disc-rot from developing in the future?

thanks for letting me know!

The fungi most closely associated with disc rot Geotrichum candidum is a facultative anaerobe, which means it does not need any oxygen to consume the polycarbonate and aluminum used in pressed CDs and DVDs. So not even a bucket of nitrogen or carbon dioxide (from dry ice) would stop it, much less the 'vacuum' in such a bag.

What it does need is water/humidity, and it grows faster with heat. So the best place to prevent disc rot is in the freezer where it's cold and all water is locked up as ice.

Note that ~25% of people are colonized with this fungi on their skin so it's not like you'd need to be a cheesemaker to 'infect' your discs.
