The stability of RW tracks is an inverse function of the number of overwrites. Which is to say, first write can be very stable - but next writes degrade the physical medium, with result similar to repeated overrwriting of magnetic media.

As you note in another message, there are variations in media durability. My guess is that poor plastic sealing is a major factor - with proper sealing, air pollutants count for nothing, and therefore temperature counts for little or nothing. [No chemical contact => No chemical reaction, therefore no reaction rate that can be determined by temperature].

I tried using CD-RW for a while, to backup working files from HD. It turned out to be too expensive - daily backups killed the CDs fast. For my purposes, adding HDs has been the most cost-effective for backup of working files. And DVD is cheap and reliable enough for backup of original program files, other older files that don't need fastest or most frequent access, etc..
