    Default Storing CDs

    Been wondering about this for a while.......

    Probably like many, I ripped my CDs to an HDD and then consigned them to the attic. Trouble is, the attic goes from being like a fridge in the winter to an oven in the summer. I've got about a thousand CDs up there, so a fair bit of moneys worth and I'd be severely dischuffed if they became somehow degraded by the temperature extremes.

    Is this a real problem or can I forget about it?

    a cool dry place with little light is usually best. Probably better in attic than a garage tho. Cased and slung under a bed is often the way

    They should be fine. You'd need some real serious extremes of temperature to do any damage. Not likely to happen in Burton On Trent but if you end up moving to Siberia you might want to take precautions.

    I've had to store mine in garages and attics over the years and the oldest ones still play fine - included recorded CDs.

    Worth bearing in mind though that if you do get them down to play/rip that you give them time to acclimatise, particularly in the winter or if your attic gets damp like ours (they absorb moisture...)

    This site gives some useful info:
    https://www.clir.org/pubs/reports/pub121/sec5/

    "If stored at a very low temperature relative to the user environment, the disc should be gradually acclimated to the environment in which it will be used to reduce stress and moisture condensation. A significant, abrupt temperature change will cause greater stress than a gradual change. Leaving the disc in its packaging will allow gradual acclimation to a changed environment. Discs used frequently should be stored at a temperature similar to that of the environment in which they are to be used. This minimizes stress from frequent temperature changes.

    Given the absence to date of relevant testing, the precise effects of storing CDs and DVDs in freezing temperatures are not yet known. Freezing and thawing may create harmful stresses in the disc because of differing expansion rates of the layers, but it is unclear how much this stress might affect the disc. "

    I would have thought the printed material would suffer large temperature change more than the actual media disc.

    When I have stored paper products in the type of environment you describe than at best "foxing" of the paper material seems to happen and quite quickly too.

    strong light and very hot temps are probably the worst probs. keep plenty of that gel pck stuff in the boxes and should be ok

    No I think its a real problem. I store a lot of collectables and they really have to be in the house within a limited temperature range. Heck even in a drawer in a colder room games and cds can start to develop temperature dulling and mould

    The humidity in the air and what happens when temperature changes is something we dont often focus on. The condensation effect then dry air can ruin the cosmetics

    The attic isnt doing them any favours and the paperwork can start getting wrinked or mould flecks developing also on the cd. So the printed material will start deteriorating faster. Even boxed up the deterioration can be surprising. Im not saying the cds will rot away but its not doing them any favours

    The attic will go very cold in winter and then very warm in summer. Too much of a temperature range and no normal airation has an effect. The minute they are boxed away in the loft you are neglecting them.

    My dad thinks this sort of thing is ok and it drives me nuts

    My attic stays pretty much same all year round... perishing but dry. Mind you Scottish roofs are built different to many in England and are double lined. also mine has about 2 feet of insulation as well. need it here with the weather at times lol

    Yep - the article I linked to recommends taking the paper inserts out of the boxes for this reason.

    Although, as I said, I have never had any major problems despite some harsh conditions they have been subjected to over the decades (well, harsh in UK terms anyway )

    That was my point, what we think is 'harsh weather' in the UK is a joke to most of the rest of the world.
