        KEENE, England - Building on research done at Keele University,
        startup Keele High Density Ltd. aims to commercialize a memory
        technology it says could store 2,300 Gbytes of rewritable
        random-access data on a device the size of a credit card. That is
        equivalent to an areal density of 86 Gbytes per square centimeter.

        \_ Thiis is complete crap. The only way to increase information
        density is to decrease the physical size of a bit, which is
        currently about 1 square micron on optical devices. The only
        feasible way to do
        this is using near-field techniques to read an write bits much smaller
        than the wavelength of light, but you can't use it for multilayer
        devices, and its somewhat like CD or DVD technology in that everyone has
        a finger in the pie.
                \_ It's possible they have developed something completely new
                   but I doubt it.  It's a hoax.
        \_ Old news.  They have nothing but a theory, and I've read some
           other stuff which says this can't be verified by calling the
           University.  This is likely a hoax at worst, a pipe dream at
           best.

11/11   Watch the History Channel today! It's got Oppenheimer and the atomic
        bomb history. Did you know at one time 10% of the entire electricity
        in the U.S. was used to refine U235 and weapon grade plutonium?
        Holy jesus! I wonder how much energy is used to get plutonium fuel
        that generates today's nuclear powered electric plant

That is equivalent to an areal density of 86 Gbytes per square centimeter. The memory system exploits the storage properties of a new family of metal alloys, said Mike Downey, managing director of Cavendish Management Resources Ltd. The company plans to license the technology to computer and storage companies. Downey described the memory system as solid-state and three-dimensional, with data stored in multiple layers. The company predicted that production costs for a 2,300-Gbyte credit-card-sized memory will be less than $50. Keele also talked of wristwatches with a memory capacity of more than 100 Gbytes. Williams has applied for patents on schemes for optical, magneto-optical and multibit-per-storage-site memories that promise to raise data storage densities by a factor of 20 or more. Ironically, Keele University closed down its electronic engineering department, where Williams worked, but now stands to earn licensing revenue from the technology developed there. Downey said many details of the technology were being kept secret as Keele High Density enters into sensitive licensing talks with a number of computer and data-storage companies. Downey said that the metal alloy Keele uses is akin to one being investigated at IBM Corp. The quoted areal density and available optical resolution imply multibit-per-site data storage. Williams declined to elaborate on whether the new material displayed a magneto-optical or a different storage effect. We plan to build a large-scale prototype in the middle of next year with one or more licensees," said Williams. Focusing is used to provide fine control of the addressing in x, y and z directions with the variable focus and transparent microscopic layers used to store data in three dimensions. The data access time for the new storage technology is predicted to be around 100 Mbytes/second. According to the company, an additional advantage over existing data storage systems is that only 20 percent of the total capacity is needed for error correction, significantly less than the 40 percent now needed for hard disks and 30 percent for optical storage. If the technology were to take hold, Keele predicts that it could give rise to portable computers capable of storing as much data as 350 present-day PCs. Theoretically, such systems could be on sale within two years, the company said. Between 1978 and 1982 he led the team that developed the nuclear magnetic resonance imaging, or MRI, medical body scanner. Discover its benefits over other benchmarks such as Dhrystone.
