    Sony and Panasonic Propose Blu-ray Disc Capacity Increase

    Sponsored Links
    Sony and Panasonic have developed a new technology that will allow the layer capacity of Blu-ray disc to be increased from 25GB to 33.4GB per layer.

    Apparently, exisiting devices would just need a simple upgrade to read all 33.4GB or 66.8GB per disc.

    To quote: "Sony and Panasonic have announced that they have developed a new optical disc evaluation technology that will allow the layer capacity of Blu-ray media to increase from 25GB to 33.4GB using existing Blu-ray laser diodes.

    This would presumably allow existing Blu-ray hardware - including Blu-ray Disc players and burners - to play the proposed discs with a simple firmware upgrade.

    Currently, disc evaluation is accomplished by analyzing disc jitter, but at higher capacity, that technique becomes unreliable. Sony and Panasonic resolved this by developing i-MLSE (Maximum Likelihood Sequence Estimation) evaluation index, which can perform the same function as jitter but at higher capacities."

    Awesome. I want BD to succeed.

    But I think not even MGS4 or FF13 have used the full 50GB of a BD.

    That is incredible news, but I thought that BR games and movies don't really come close to the capacity of the BR media. It would be awesome if it makes games and movies better, maybe allow for higher resolutions than 1080p. I know it sounds crazy and impossible with current televisions, it could give the PS3 a longer lifespan.

    Although this is a great news capacity wise (even though some of you already stated that no game reached the 50 of the BD, but i remember MGS5 did it).

    I feel it's not so much that good when you really think about the name "Maximum Likelihood Sequence Estimation". doesn't that mean that the disc readers well "keep estimating" all the time? wouldn't that decrease the performance? even speed? and oh my god, the most important thing the lifespan of the BD reader?

    I'm just speculating...

    This is great news because while no games have gone to the 50GB limit, wouldn't it allow games which had a little over 25GB to keep all the content on? I'm no expert, so please call me on it, but discs come in either 25GB or 50GB, the latter being more expensive. Now it makes sense for developers to cut down the content if it comes nowhere near the 50GB limit does it not?

    My reason is being that you pay for 50GB and not 27GB or 32GB etc, it is not cost effective, and the more profitable option would be a slimming down package. Now, say a game originally had 29.53GB of data, it can all be included on this new media disc instead of losing the 4.53GB in order to make the cut off. Can someone with more knowledge either verify this or call me on it?

    P.S: Also, think about this move as a way to provide more space for 3D gaming as promised by Sony for 2010. 3D takes up a lot more space than the same data without the 3D capabilities. Just something to ponder

    It would allow for extra content that is usually in the form of a second disk all to be included on one bluray.

    I dont know if games are actually coming close to the capacity of current disks anyway.

    Sound pretty cool. I bet it will be usufull for the 3D Blu-Ray movies... Games... well you can always swap disks right.
