~~~ can CDs withstand some cold from the air conditioner? ~~

by kin3200 - 6/3/09 12:49 AM

on one occasion, i placed my store purchased cds in a simple rubber maid box next to the ground level air conditioner (my apartment is built that way) which blew at it through the night till morning for 8 hours full power which i then turned it off and the room goes hot again, i thought it wasn't a problem since i remembered that only heat is harmful to discs but now from reading the linkie it seems that i'm not suppose to leave it anywhere below -10c. so are my discs damaged?

i was too tired from unpacking and cleaning my new home to give a damn, so i left it there and the next morning the interior of the rubbermaid box was quite damp and cold, some droplets of water even, though my discs were all secured either insides dvd cases or the caselogic dvd holder, but now i have to say i'm worried sick, i want to find the dumb ass who designed and built my apartment with the ground level air-co anchor so i can rip out his lungs.

please tell me my discs are ok...*sobs*

thanks sooo much!!!!

Shock treatment

I can't promise anything here but common sense says, you should allow that CDs return to normal room temperature. Once, you get into extremes or outside specs, it may well work but not all the time. You then have to consider the wear&tear side effects, the age and just how quickly from laying there before put to use. Damage is damage no matter how it got it, it won't necessary heal itself. Considering the failing of some disks under normal conditions and/or kids in the house, they fail w/o being cold. So, don't rush using cold disks allow them to warm-up abit, akin to you getting up in the morning. :)

My concern is the moisture.

It's time to get them dried out. I won't duplicate content from these links:

http://www.google.com/search?hl=en&q=Recommended+Handling+and+Storage+Conditions+for+CD-R+media

http://www.mscience.com/longev.html writes about water and more.

-> Dry it out and then repack it with some dessicant. Here's a source:
How much dessicant? -> http://foodsave.net/controlled_atmosphere_requiremen.htm
(now to amazon.com for some.)

CDs and Air Conditioner

Really you answered your question..what is -10 deg Celsius...quickly I calculated, that would be 51 deg Fahrenheit. I doubt the AC was that COLD. AC usually drops the temp no more than 15 degrees.

Dry them out on a paper towel...wait as Ron states till they warm up. So they do not get stress due to the heat from the drive and the laser.

I would always worry more about heat and warping and de-lamination then the cold. Unless you put them in the freezer and PLAYED Frisbee.
