    HVD Format Gains Backers
    Holographic Versatile Disc (HVD) technology may still sound like
    science fiction, but it has just edged a little closer to reality
    after acquiring the support of six Japanese industry heavyweights.

    Fuji Photo, CMC Magnetics Corporation, Nippon Paint Co, Optware
    Corporation, Pulstec Industrial and TOAGOSEI have announced they are
    behind the venture, and claim that the technology could come to market
    soon after 2006. So, with the battle between new disc formats Blu-ray
    and HD-DVD still raging, consumers may have an alternative to both,
    sooner than they might have imagined.

    The concept behind HVD is something called collinear holography which
    combines a reference laser and signal laser on a single beam, creating
    a three-dimensional hologram of data fringes. These fringes, the
    Alliance purports, enable discs the same size as DVDs to store more
    than one terabyte of data (1,000GB) or roughly 200 times the capacity
    of a single layer DVD. Data transfer rates are also claimed to be very
    high at over 1Gbit/sec (40 times faster than DVD).

    By comparison, single layer Blu-ray discs hold just 25GB of data and
    dual layer 50GB. HD-DVD is even smaller, holding 15GB on single layer
    and 30GB on dual layer. Of course Sony has demonstrated an eight layer
    Blu-ray disc with a capacity of 200GB, but even that is just one fifth
    of that capacity that HVD hopes to achieve. Intriguingly, the HVD
    Alliance also claims high level compatibility with DVD and CD discs,
    so you shouldn't have to throw out all your old software.

    Now there could be an argument for saying: who needs one terabyte of
    data when you can store up to 50GB with dual layer Blu-ray? Yet
    history proves that consumers always manage to fill these new storage
    capacities and with two hours of HD programming expected to require
    between 15 and 25GB, there is a compelling argument for HVD.

    This is very misleading, as the name "HVD" has already been taken by the
    Chinese 720p high-definition format that has been available since last
    year. Whatever this holographic storage system is, they're going to have
    to come up with a new name.
