proven to last 1000 years..
so back in the year 1014 (52 years before the battle of hastings) someone invented a stone based circular disk that could be read in DVD players..............
hmmmmmmm
well i can bend a disk and snap the thin layer of slate in the middle.. takes only 2 seconds....
i wonder if M-Disk will guarantee the value of the contents if lost., id love to see my claim if i lost my bitcoin priv keys due to cracking the stone layer
i bet the manufacturer spent years banging his head against a brick wall for a permanent solution to data storage..
