Question About Effects of Heat/Sunlight on CDs/CDRs

[Kelly Penley <one_zep_hed1970@xxxxxxxxx>]

Hey FBOers,
    I figured that my question will get a thorough answer here. So here it is: I
know that you're not supposed to leave your CDs in the sometimes sweltering 
heat of
the your car interior, but is it really that big of a deal? 
    Years ago when I was just a young know-nothing, I left my friend's uncle's 
vinyl
copy of TSRTS in the backseat of my '70 Road Runner, for over a week. I had 
borrowed
it to make a cassette tape of it, and I kept forgetting to take it out of the 
car at
the high school. Needless to say, that was a bad way to learn about heat 
warpage.
Man you could have surfed to Kasmir on those waves! lol. Anyway, I did buy him a
replacement, which (being low on funds) defeated my original purpose.
    I saw how vinyl reacts to that level of temperature, but I have never had 
any
noticable similar reactions with my regular CDs, and I keep at least 10 
selections
in my car at all times. Has anybody had a "regular" CD warp from heat?
    I'm actually probably beating around the bush, because my main concern is 
with
CDRs. I have heard that direct sunlight on the surface of a CDR can make short 
order
of one. Although I don't plan on laying any out in the sun or anything, I would 
like
to keep some of my Zep CDRs in my car where I listen to them most.
    How bad of an idea would it be to leave a couple of them Zeps in my car 
where I
can enjoy them? For reference, I live down south in North Carolina, and it can 
get
pretty toasty inside of the Mazda on a Carolina summer's day.
    Is warpage the only factor with the heat, or is there an ink degradation 
issue
too? Also, if warpage is a legitimate concern, how much warp will it take to 
make an
audible difference? Would you be able to "see" that amount of warpage just by
looking at the CD?
        
        Just a Ripple In the Ocean,
                                 Kelly
