    Blu-ray disc hits 100GB

    TDK has developed a prototype Blu-ray disc that can store twice as much data as current iterations of the next-generation DVD format--and record it twice as fast.

    PC World reports that the 100GB disc, unveiled at a TDK exhibition in Tokyo this week, can record data at 72 megabits per second, double the 36 mbps rate of current Blu-ray discs. To achieve the higher capacity, TDK added two additional recording layers to the disc to take it up to four layers.

    TDK's announcement comes on the heels of last week's news that Toshiba has created a three-layer read-only HD DVD that can hold 45GB of data. HD DVD is a competing format to Blu-ray Disc and HD DVD's maximum capacity of 30GB had been viewed unfavorably against Blu-ray Disc's maximum 50GB capacity on a dual-layer disc.

    With the ever-evolving format battle heating up so fast, we're just waiting for a 12-layer disc that can double as an MP3 player and a movie screen.

    Holography breaks through the density limits of conventional storage by going beyond recording only on the surface, to recording through the full depth of the medium. Unlike other technologies that record one data bit at a time, holography allows a million bits of data to be written and read in parallel with a single flash of light. This enables transfer rates significantly higher than current optical storage devices.

    Combining high storage densities, fast transfer rates, with durable, reliable, low cost media, make holography poised to become a compelling choice for next-generation storage and content distribution needs.

    In addition, the flexibility of the technology allows for the development of a wide variety of holographic storage products that range from handheld devices for consumers to storage products for the enterprise. Imagine 2GB of data on a postage stamp, 20 GB on a credit card, or 200 GB on a disk.
