To quote an article I recently wrote (but which has not yet been published) --
<NFPA 232 Standard for the Protection of Records 2000 Edition, Appendix A, "Explanatory Material" lists the requirements for records protection equipment as tested in accordance with Underwriter Laboratory (UL) 72, "Standard for Tests for Fire Resistance of Record Protection Equipment."
Records protection equipment is classified in terms of an interior temperature limit and a time in hours that the specified interior temperature and humidity limits are not exceeded when equipment is exposed to a standard fire test for the length of time specified. This time is rated as 2 hour, 3 hour, or 4 hour. The equipment is rated using a class consisting of the temperature limit and the time rating. Thus, a Class 125/ 2 hour rating means the tested material was protected for two hours in 125 degree internal temperature. The following three temperature and humidity limits are employed:
* 125°F with 80% RH, which is regarded as limited conditions for floppy disks
* 150°F with 85% RH which is regarded as limited conditions for photograph, magnetic, or similar nonpaper records, such as microfilm
* 350°F with 100% RH, which is regarded as limited conditions for paper records.>
CD/DVD media is stored either as the same as floppy disks or the same as magnetic media. I would go with the floppy disk similarity because there are more plastic components to CDs/DVDs than to magnetic tape or microfilm, and various plastics have various combustion or melt rates.

Can anyone give me an idea of how much heat a CD/DVD can tolerate before it
becomes unreadable? I'm developing a disaster recovery plan and am trying
to justify purchasing fire-proof filing cabinets.
Thanks.

Possibly you are channeling the wrong spirit :)
I trust CD's
I trust platters
I trust cave walls
I trust all media to do what it is supposed to do.
Recognize the limits and value of each and don't expect it to do more than
it can do.
Yes CD's have issues
Yes Platters are slow and expensive
Yes mocrofilm is becoming an increasingly arcane technology
yes finding a good cave wall is tough (and don't get me started on finding a
good cave painter. Oogar was probably the best but then the critics showed
up and the entire genre went south)
I always like the idea of NORSAM. Anything that takes an electron microscope
to read the media has to be way cool.

>>I've seen and heard enough about potential data loss on CDs to be a
bit reluctant to trust CD as a medium.<<
I don't recommend them, I recommend film. However, I just couldn't
resist the chance to point out that film LE is as much an estimate as CD
LE. And, as I have said before, the only completely proven media for
record storage is cave walls, and they only go back a few thousand
years.
