not sure if it will be news to everyone but here it is anyway
just in case
" a new type of CD-R has been developed by FujiFilm to offer stronger longevity when backing up digital photographs.
the company claimed the disc is 10 times more stable than cheaper discs
and should last longer before the photos need to be transferred to a new piece of media.
the photo disc has a coating that protects the recording layer from ultra-violet and solar radiation that can lead to data loss.
the new discs are just as capable as ordinary discs, holding up to 700Mb
and can be recorded at up to 52x speed "

No,. I had not heard this.. sounds good. :)
I've been using rather standard disks.. can't seem to figure what are supposed to be best.

That is interesting about the protection from UV light and solar radiation. But to me that sound like more hype.
Personnally my "stored" CD are keeps somewhere light does not get to. I don't think I would worry too much about problems caused by UV light and solar radiation.
From the web pages I've read about CD-R longevity what makes the difference is the composition of the plastic. Certain forms of the plastic are more stable than others.
The catch is that CD-R don't list what they are made of and to be able to tell you have to know where the CD-R was manufatured and that is encoded on the CD-R that you don't have access until after you buy it.

Well, I do have a number of CD-R discs laying around in my appartment that are starting to look yellowish instead of silver after laying in the sun for too long. So I can imagine that sunlight and especially UV damages CD-R discs.
I also keep my CD-R and DVD+R and -R discs with backups of my photos in a drawer in the dark, so they won't be affected by the sun. I don't know how long they will last, but I bet that when you keep CD and DVD recordables in a cool, dry and dark place they'll stay OK for many years.

Don't forget humidity, fungus/bacteria can eat into the layers. I agree with Steven, the UV protection is marketing and not really useful.

At 48mb's a raw file, my backup is DVD-R, kept in a looseleaf on a shelf out of the sun.

I heard long ago that the CD-R DVD-R had a relatively short lifespan.
I have made it a habit to put the date the media was recorded onto the label and have checked back to see if the data was good even a few years later (I have all my paper documents backed up (scanned) onto CD and don't want to lose them either.
I have yet to have a bad media in the 5 years of backing my data to CD but I still check back every year to make sure all is good.
(I simply copy all the data to my hard drive, if I get errors, then it is time to start thinking about re-copying the media)
