  • Blu-ray Storage Capacities To Keep Climbing


    Pioneer has announced plans for a one terabyte (1TB) Blu-ray disc that could be on the market by 2013.

    With a 400GB disc already ready for launch and a half-terabyte disc expected to follow shortly, there may be some questions about how such an abundance of storage can be used.

    One answer may be the advent of upgraded high definition standards that take up even greater amounts of disc space.

    The possibility for progressively increasing to higher densities was a major reason that Blu-ray won over its rivals.

  • Pioneer 400GB Blu-ray discs will play on PS3


    There are undoubtedly pros and cons to having a single disc that can pack in 400GB of data – movies, music…whatever you can throw at it.

    Pioneer is preparing for release a 16-layer Blu-ray disc that not only offers this colossal storage capacity but will play back on most current standalone Blu-ray players, including the Sony PlayStation 3.

    The manufacturer insists that the read-only disc will be backwards compatible with existing players because the specifications of the pick-up head (PUH) of the disc are the same as those for blank BD discs.

    Currently, Blu-ray discs are either single layer 25GB discs or 50GB dual-layer discs.

    The new multi-layer disc is based on current Blu-ray discs but made from a new material of reflective layers of Dielectric.

    It is read-only (ROM) but there are plans for rewritable discs by 2010-2012.

    What is still not clear is whether current players will be able to read all 16 layers of the 400GB disc, rather than just the first two.

    The company also added that it will begin manufacturing 40-layer 1TB discs in 2013.

  • Pioneer develops 400 GB Blu-ray disk


    Pioneer     has developed a Blu-ray compatible disk that can hold 400GB of data on 16 layers.
    The company currently only has a read-only disk available but expects to be able to produce recordable discs.
    Each of the layers can hold 25 GB of data – equivalent to one single “standard” Blu-ray disc layer.

    Multi-layer disks have existed for a while. Normal DVD players and burners are usually able to read and write to dual-layer disks.
    It has been a challenge for Pioneer to get a clear signal from each of the recording layers of the disk, without picking up distortion from other layers.

    The electronics company invented a disk structure that reduces crosstalk from adjacent layers, resulting in a 16-layer optical disk that can playback high-quality signals from every layer.
    No infomration has been given so far on availability and pricing.
