We mentioned the company INPHASE a couple of times now due to their holographic storage technology. While HD-DVD and Blueray standards are now fighting for two years to become a standard the competition is picking up the really quickly. INPHASE just announced at the CES the first 300GB holographic disc, and that's just the first generation device ! This will be followed a family of products ranging to 1.6 terabyte (TB) capacity in 2009.
I'm personally getting really annoyed over the HD-DVD versus Blu-ray fight in the industry .. in the end it's all about who's gonna make the most money, monopolize the market and meanwhile this HD storage technology might get outdated before it was ever launched. At the end of this year a couple of hundred movies will be available .. but the devices that will play them .. will they be affordable ? I don't think so. So add another year for mainstream availability.
LAS VEGAS, NV -- InPhase Technologies, the leader in holographic data storage, announced today that it has successfully demonstrated a data density of 200 gigabits per square inch, significantly higher than any other optical format. InPhase achieved this breakthrough by using its patented polytopic recording method, which will be implemented in all generations of the Tapestry drive family. The first generation drive, targeted at a 300 gigabytes (GB) capacity on a single disk, will be available in 2006. This will be followed a family of products ranging to 1.6 terabyte (TB) capacity in 2009.
Holographic storage delivers high capacity by recording data throughout the volume of the recording material, and not just on the surface. A data page of approximately 1 million bits is recorded in one exposure of the laser. Each data page is located at a unique address within the material and several hundred pages of data, each with their own unique address, are recorded in the same location of the medium. A collection of data pages is referred to as a book. This new recording technique enables more holograms to be stored in the same volume of material by overlapping not only pages, but also books of data. This dramatically increases the storage density.
This new recording method is implemented in conjunction with an optical architecture developed by InPhase, which uses optical lenses with a high numerical aperture (NA). The combination of the new recording method and high NA lenses results in a smaller page size that provides a 10X increase in achievable data density. This also increases the data transfer rate, and InPhase has demonstrated a transfer rate of 27 megabytes (MB) per second at density.
InPhase was able to deliver this latest innovation through a $2.77 million grant awarded in 2003 by the National Institute of Standards and Technology's (NIST) Advanced Technology Program (ATP). The purpose of the grant was to develop advanced holographic recording technology that would lead to the commercialization of the first 1 TB holographic data storage system. This grant was the second that InPhase had received from the ATP in 2002-2003. The Advanced Technology Program has been a critical source of funding for breakthrough technology developments that have the potentially broad economic benefits to the United States.
INPHASE also has some movies on-line showing the first prototype, definitely worth checking out !
