I have 100s of mp3 files I've ripped (mostly at128kbps which sounds fine 2 me) and want to make backups.
Are storing CDR backups of data and mp3's going to be adequately
protected in a Fire-safe such as the one I have that says temps inside
will remain below 350F for one hour in a fire environment?
Also how do regular (pressed) CD's fare (unprotected) in a fire envirironment
compared to other media?

I guess its better to store important data at an alternative site? I have a
large collection of mp3s I've ripped, data, and digital images. About
25 CDR's worth of it, so I'd like to find out how to keep it safe.
DVD-R's are probably even better for archival purposes, but my PC only
has a regular CD burner.
