"Scientists are reporting successful tests of a new memory device that could
allow terabytes of data to be stored without corruption for millions of
years.

The device is an iron nanoparticle, 1/50,000 the width of a human hair,
enclosed in a hollow carbon nanotube. 

The iron can be shuttled back and forth within the tube as an effective way
to store data.

The team says it is achievable to build storage devices capable of carrying
a terabyte of information per square inch, making it more effective than
current techniques. 

However, the data will also be almost incorruptible and should remain
available for a billion years or more.

Current memory technologies are nowhere near as long lasting. Conventional
flash memory usually fails after around three to five years.

As an example Alex Zettl, one of the team behind the invention, notes that
the Doomsday Book written on vellum has so far lasted over 900 years,
whereas the digital version of the book, encoded in 1986, failed in less
than 20 years. 

Details of the device will be published in scientific journal Nano Letters
later this month."
