So it is 21st century digital microfiche? Clever. I do know museums will probably line up for this stuff - standard CD-ROMs start to rot after 10 years and DVDs are better but relatively untested.

I wonder how much FEC is built into them. (In other words, what is the biggest scratch you could put into it without losing data.)
