[filmscanners] RE: No more Kodak CD-R's

I see that TDK have a CD-R product designed for photo storage, although I
haven't seen them in stock anywhere. I doubt the discs are any different
from their other high-quality data disks - they've just got more space for
writing on. TDK reckon CD-Rs have an archival life of 100 years with careful
storage. Also they reckon we don't need gold.

>From TDK CD-R faq:

"Is is true that silver CD-Rs are not as reliable for long-term storage as

Short answer: NO.

Long answer: In TDK's Reflex Mirror Tuning, the pure silver reflective layer
is sealed with a highly refined protective coating. The components are
non-reactive with silver and protect against reactions with both the dye
layer and the lacquer overcoat. Bonded in a hermetically sealed structure,
the silver layer is also completely protected from reactions with
atmospheric oxygen. With use of this protective layer, third-generation
Certified Plus CD-R match gold CD-R in long-term archival stability, and
carry a rated life span of more than 100 years."

Personally I'd like to know about independent testing, although any tests
will almost certainly have been done by elevating temperature & humidity to
simulate the passage of time. Epson did that with inkjet prints only to find
their ink & paper combinationreacted to environmental ozone and under
admittedly unusual circumstances prints started going orange in months...

BTW there is one important issue raised in another TDK faq - how long do you
think the hardware is going to be around for? (All I know is my old prints
are fading, my slides are getting spotty & I've had two hard drives die in
the last year!)
