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."

    ...and heated to 1,300 to 1,500 degrees Centigrade... for 24 hours...

    I certainly hope they can improve those figures. From a manufacturing standpoint, that sounds very expensive.

    I have a bad feeling about this...
  2. A horse in my wallet. by SharpFang · · Score: 5, Insightful

    Well, say what you want, right here with me, in my wallet, I have a horse. Smaller than a quarter.
    Precisely, the complete genome sequenced and sorted. On a 2GB MicroSD card.

    "A lot of books" is an odd abstract that doesn't really impress me. But the idea of a full, unabridged, complete set of information which describes a real lifeform in full, contains the program of all the life functions, all the complexity of neural system, all the mysteries of instincts and social behaviors, the complexity of senses, the strength, immunity, lifeforce of a powerful creature - all this potential, described as a bunch of files consisting of rows upon rows of letters AGCT (gzipped).

    Sure we have no technology to reproduce a living creature from this data alone. But that looks like a really small problem compared to all the incredible knowledge achieved through billions of years of evolution, to solve all these problems of creating a standalone, self-repairing, self-replicating, self-defending, and quite pretty to that, piece of "biotechnology" - actually, the solution to re-creating it from that data (only on different media) is right in that data. We just can't really use it.

    250 high quality movies, in some future? blah.
    A horse in my wallet, now and today, that is what impresses me, really.
