Never forget. Microscopic iron crystals moving within carbon nanotubes could hold computer data permanently.

That embarrassing home movie of you naked in the tub could still be around millions of years from now, along with your less-than-eloquent posts on Facebook and Twitter. Researchers have developed a new technology based on carbon nanotubes that promises to permanently preserve individual bits of data, such as those found on computer hard drives and DVDs. If so, the technology could lead to data archives holding the entirety of human thought and communications potentially forever.
As our technological society has progressed, storing and retrieving data has actually grown more difficult. One notable example is the Domesday Book, a record of English settlements compiled by William the Conqueror in 1085. The document survives in a secure, environmentally controlled facility, but a digitized version produced in 1986 lasted only 20 years: Magnetic patterns embedded in the computer disk degraded steadily over time. Likewise, home movies shot on Kodachrome film have preserved family memories for more than 60 years, whereas videotapes can deteriorate in less than a decade. And some DVDs have shown signs of image loss even more quickly, because their plastic and glue layers have turned out to be relatively fragile and are vulnerable to sunlight exposure and mishandling--a phenomenon called DVD rot.

Seeking something more permanent, a team of physicists and materials scientists has looked to the nanoscale. Reporting this month in Nano Letters, the group describes a technique of placing a single iron crystal only a few billionths of a meter wide inside a hollow carbon nanotube. Like diamonds, nanotubes are among the most stable structures in existence. Once inserted into the tubes, the iron nanocrystals act as data bits, physically sliding from one end of the tube to the other in response to an electric current and in the process registering either a "1" or a "0" in the binary language of computers. "Nothing could be easier, electronically speaking," says physicist and co-author Alex Zettl of the University of California, Berkeley.
Zettl says the technology will require further tests, but results from both lab experiments and theoretical models show with "high confidence" that the device can retain data indefinitely. He says commercialization of the device--which would probably look something like a flash drive--will be challenging, "going up against a mature electronics memory industry." But given the potential impact, he says, the incentives are high.
Materials engineer Mark Spearing of the University of Southampton in the United Kingdom calls the study "well conducted" and the technology "ingenious." Nothing is permanent, though, he says. Such a device could fail for any number of reasons, says Spearing, some of which may be currently unknown.
“Better than Viagra”
All that will still be missing is Obama’s birth certificate.
Bill Gates will find a way to make it unreadable within 10 years.
Better than Viagra
Better than that, the school threat of “that’s going on your permanent record” will come to fruition.
(not to mention a backup of ones’ wife having a backup of everything that she remembers and you don’t )
Gotta invent stronger magnets (I can live with the first, but not the second)
Not to mention all of my less than eloquent posts on FR.
Ping
At lest I nevver mispelled nothing
The data may be intact after a billion years, but the “language” and “syntax” of the data will be long-forgotten and the data will be incomprehensible to anyone later on... LOL...
Also, the “reader device” may not even be around any longer, either, not to say anything about the protocols for transferring the data to an intelligent device to “see” it...
and like all HD’s, there’s a chance it will crash. Let’s just all breathe a sigh of relief that Vista wont be around.
But you will need the Windows version 22,500 with SP123 and its Carbon Media Player 99 to be able to get to that data
reversible??
Carbon-RW?
plus the files will be all DRM accdg to Googlesoft and you wont be able to access them.
Iron crystals?
Ahh. One electromagnetic pulse nuke would wreck that plan in a hurry.
What a great new medium. Isn’t it a shame what the guy’s first thought was when presented with this. The complete knowledge of man, and he’s focusing on ghastly home movies and twitter notes. Good grief!
Study Clarifies a Depression Risk
FReepmail me if you want on or off my health and science ping list.
he thought he was giving the world the computer for the Enterprise and its written up all about twits tweeting tweets
Yep, I agree.
Western Digital will come along and give even this media a bad name.
LOL :)
