They've been around for 5 years and good quality brands support them. Maybe they won't last, but it's a better gamble than a pack of cd-r discs from walmart!
Let me be a little more explicit. Stratoscope was willing to purchase the disc on the promise that Stratoscope would personally be able to read the disc 1000 years from now.
IOW, not just that the data would be there and readable, but that Stratoscope (the person) would also have lived another 1000 years.
