How much?

Posted: Fri Sep 01, 2006 9:36 amThanx, Matt.
Looks interesting ..... but ....
How is proper handling defined?
And how do Kodak define a year in this context? They've been known to redfine the terms "day" and "year" in order to make it look like their prints last a lot longer than they do.
I think it's always a good idea to treat any sort of marketing claim with a degree of cynicism.

and it’s owned by Kodak 
and it’s owned by Kodak Posted: Fri Sep 01, 2006 2:10 pmAnything fr DVD's that will last 10yrs would be good enough.. But they make some bold claims.
Be interesting to see price also.
This has reminded me its time for a backup..

Proper handling is defined as 'Kept in a biologically free vacuum chamber'.
The moment you touch it the warrenty is void.

Actually, the "good" DVD-R's do that already, easily. With good I mean metal-azo dye based. Like the Mitsubishi Chemical Corp made ones.
In fact, stability of the dye isn't really the issue (unless we're talking cheap crap, or RW's). It's mechanical failure we have to worry about, esp delaminating., due to undue stress (like when trying to get them out of the brain-dead case).

Sounds about right.
Posted: Sat Sep 02, 2006 12:02 pmSo, is the long time frame valid for data written with a $ 30.00 CD writer in your home computer or a $ 30.000 unit down at Kodak's Lab or a $ 200.000 unit in the film studio? 
Posted: Sat Sep 02, 2006 3:40 pmAnyone know where I can buy a new betamax player to play some of my dad's betamax tape collection? Just seeing if they live up to their 50yr lifetime claim...
I'm sure you can draw the parallels....

Posted: Sat Sep 02, 2006 5:49 pmDye stability IS the biggest problem with CD's and DVD's.
All tests show that quite conclusively. Google for CD and DVD longevity and you'll get a few studies. Nist's one is best.
Mechanical failure only occurs with excessive spin rate. I've seen one Microsoft office CD explode in a drive and one Linux burnt CD.
The others have been CD's and DVD's spun up with a dremel tool, then knocked onto the floor.
They were spectacular and rather dangerous in terms of sharp high velocity polycarbonate.
