We routinely archived to CD and create two copies of each archive. Since 1996, the only reason we've had to dig out the second disk is because someone lost the master, not because it became unreadable. No CD has failed on us. We've always used 'branded' disks, mainly Sonys, Verbatims and TDKs. I think we've got several hundred Fujis in use at the moment.
I'm quite careful as to how we make the disks, not using maximum 32x or greater speeds, but normally at x12 or x16 speeds. IMHO it's the out-and-out quest for faster writing times that could be more of a problem. The latest crop of CD-Rs go up to 52x which implies they'd write a full CD in under two minutes. Isn't that impossible?
Having said all that, DVD-Rs scare the living daylights out of me but we've now started archiving to these just because of the increased capacity. However, the propsect of ever losing nearly five gigs-worth of images or data is just awful and we're writing two copies of each DVD at present and I intend to check a sample every three months to make sure I can read files on them.

Hi
If you are dutifully backing up your images to CDR, you might want to have a look at this article in 'The Register' <http://www.theregister.co.uk/content/54/32593.html>
It only has limited info, but I think confirms what many of us suspected.
