Read this today in Scientific American:

"Really Long-Term Memory
Preserving information for future generations has prompted some concern for digital archivists [see “Ensuring the Longevity of Digital Documents”; SciAm, January 1995]. For instance, today’s memory cards, holding 10 to 100 gigabits per square inch, last only 10 to 30 years. A solution could lie with an experimental memory device based on an iron nanoparticle that travels inside a carbon nanotube between two electrical contacts; an applied voltage shuttles the nanoparticle between the contacts. The device, described in the June 10 Nano Letters, can hold one trillion bits per square inch, and theoretical calculations suggest that the system could remain thermodynamically stable for one billion years. Don’t bother with the extended warranty."

Imagine the lucky Milkyway mammal that will rediscover "Miss Modular" on one of these storage devices in a billion years. The song will probably still sound both retro and futuristic at the same time even then.
