Coming Soon, 250 DVDs In a Quarter-Sized Device

Several readers have remarked on a new technique developed by scientists at UC Berkeley and University of Massachusetts Amherst that has the promise of achieving storage densities of 10 terabits per square inch. "The method lets microscopic nanoscale elements precisely assemble themselves over large surfaces. ... Xu explained that the molecules in the thin film of block copolymers — two or more chemically dissimilar polymer chains linked together — self-assemble into an extremely precise, equidistant pattern when spread out on a surface... Russell and Xu conceived of the elegantly simple solution of layering the film of block copolymers onto the surface of a commercially available sapphire crystal. When the crystal is cut at an angle... and heated to 1,300 to 1,500 degrees Centigrade... for 24 hours, its surface reorganizes into a highly ordered pattern of sawtooth ridges that can then be used to guide the self-assembly of the block polymers."

Nice, hopefully coming soon

This seems like it has some potential. Hopefully it will make it out of the lab considering how many times I've seen the promise of amazing technology only to find that eventually it isn't practical or has some sort of manufacturing limitation. Oh, and while you're at it, when you do create this "new technology" don't riddle it with DRM issues.

Sorry, probably not any time soon.

Not because of the tech or DRM or anything, but because this is not a new storage medium as most of the comments below seem to indicate, but because it is a new METHOD of creating storage.

From TA (Yes, I actually RTFA [sometimes, but I don't make it a habit]), it appears to be a new way to create semiconductors. This process would be used to create RAM, microprocessors, or other semiconductor manufacturing. Think of it as being able to create a 10 TerraByte RAM stick the same size as a 8 GigaByte ram stick now.

Furthermore, the heating process is not used for each set of RAM chips created. I heat up one huge crystal and then use it as a bed to create a large plate of semiconductor material which I can cut multiple RAM chips. I no longer have to use the expensive nano lithography to create chips. I only need one bed to make many, many plates. By changing the heating process, I can create one bed for RAM chips, another for microprocessors and another for a custom chip.

Why won't we see it soon, then? Because chip manufacturers already have tons of money invested in nano lithography and won't be willing to just drop it. The author seems to think that since it only replaces the nano lithography and harsh chemical processes that everyone will jump at it in order to make cheaper chips. I am not so optimistic, but would love to see it.

Re:DVDs

We're living in the future. The thought of a library fit onto a quarter-sized device makes me think of that scene from Gene Wolfe's science fiction masterwork The Book of the New Sun where the curator of the Earth's largest and most ancient library says:

There is a cube of crystal here --- though I can no longer tell you where --- no larger than the ball of your thumb that contains more books than the library itself does. Though a harlot might dangle it from one ear for an ornament, there are not volumes enough in the world to counterweight the other.

The development of such small memory is a significant step forward. Just think about how the writings of the human race can be better preserved if it all fits on a small, lightweight and easily duplicated device. It could be spread all over the solar system as protection against all manner of cataclysms. I wonder how long it stays readable though, before it succumbs to some kind of rot.

Re:A horse in my wallet.

That's probably about 1/2 of the information required to reproduce a horse. The genome isn't everything, even if it were complete (which I doubt, because repetitive segment of codons are beyond what I believe is our current ability to sequence).

But *if* you had the complete genome, including the mitochondiral sequences, etc. it still wouldn't be enough. You also need the environment to raise the genome, which includes not only mechanisms for feeding it, but an unknown but large number of prions which are required for proteins to fold correctly. Not all proteins require such assistance, but many do, and without them you can't create a live horse...or any other mammal, probably any other chordate.

I'm guessing that the genome is half the information needed. It could be considerably less than half. (Or, of course, more. I can't even tell if I'm being conservative.)

Note that the genome carries practically all the information for the variation between horses...or between horses and zebras. But this isn't at all the same as half the information.
