I would've defended myself earlier but I was out of town. Sorry about
"cyanoacrylate" it was the first "cyano-" word that came to mind and I used it
as I am a very busy man (snort snort).

My experience with CDR failures comes from working at my college radio
station, where we have used CDRs and MDs to play promos, PSAs, and whatnot for
some time now. 
Your explanation of the "pause" effect is an important point. Every time we
play a CD on the radio, it usually ends up being cued in 'pause' mode for a
lengthy period of time beforehand. I didn't think of this when we started
having problems, and I should have. Oh well.

We left a DYSAN blue CDR out in the sun by my window for a day and a half and
were unable to write on it afterwards, so I have had that experience as well.
This is no less anecdotal than any evidence not from a laboratory, I'll admit
to that.

Several CDRs I own have held up to quite alot of physical abuse, being dropped
and scuffed etcetera. So I agree that they are kinetically very resilient. But
I saw a few too many CDRs die at my radio station from everyday use to not
feel the need to bitch.

The durability of a CDR is very dependent upon the brand and the speed (4x,
6x, or 8x) at which it can be written. 8x speed CDRs have just come out... I
wonder how these will hold up.
