' In the year 2108 archeologists will not have a hard job when it comes to finding data...'

yeah, they'll have a hard time finding equipment to read these weird round objects with!

I call BS. First of all, the discs will go bad before 100 years. Second, no company will be around to check in 100 years because the world will go to hell in a handbasket first (think wwiii)

This seems an incredibly optimistic projection by Kodak, as the only way to test such a claim would be to burn the media at its rated speed, then do a 100-year study on it's longevity/data degradation.

To test for longevity you can create physical models, for instance you can develop a burn-in technique (baking the media at temperature changes at varying intervals) to create the equivalent effect on a media of laying around for say one year, use your model to extrapolate your result for 2, 4 or 10 (you name it) years to validate your model and determine your accuracy, precision, etc, then you can predict 'x' amount of years with a 'certain' level of confidence without having to wait x years. You could also study the data degradation per unit time, obtain a characteristic curve of degradation as a function of time to make your predictions.

Mitsui sold CD-r's with a 100 year guarantee ten years ago..it's nothing new. Mitsui's discs were (are) tested using a method similar but much more extensive than what eruiz mentioned. 100 year life is a reality now and ten years ago.

What? When did Kodak (re)enter the optical disk business?
Credibility meter reading......close to zero.....
