Blu-ray Discs Can Fit 128GB in New BDXL Format

By - Source: Tom's Hardware US | B 36 comments

A third and fourth layer can expand Blu-ray Disc capacity up to 128GB.

Having 50GB on a single disc helped give Blu-ray the edge as the optical format of the foreseeable future. Now that number gets bumped to 128GB in a new specification announced by the Blu-ray Disc Association.

The specifications for 128GB discs is called BDXL which is targeted primarily at commercial segments such as broadcasting, medical and document imaging enterprises with significant archiving needs. Write-once BDXL will come in 100GB and 128GB capacity discs, while rewritable ones will top out at 100GB. The discs reach these capacities by incorporating three to four recordable layers.

The Blu-ray Disc Association also announced another new standard, the Intra-Hybrid Blu-ray Disc (IH-BD), which incorporates a single BD-ROM layer and a single BD-RE layer. This will allow the user to view, but not overwrite, critical published data while providing the flexibility to include relevant personal data on the same physical disc.

Because both BDXL and IH-BD are specially designed formats with specific market segments in mind, newly-designed hardware is required to play back or record BDXL or IH-BD media. However, because the new media specifications are extensions of current Blu-ray Disc technology, future BDXL and IH-BD devices can be designed to support existing 25GB and 50GB Blu-ray Discs.

    yeye still too expensive...
    it's cheaper to buy a usb hard drive and move data everywhere.
    Even backups with actual hard drives it's possible with the hdd's prices dropping.

    Where's my BD-R/BDXL-R drive? And why hasn't it replaced my dvd-r/rw yet?

    Playstation 4 will probably be BD-XL, the expansiveness of gaming environments and characters could be amazing not to mention the lengths of games with 128GB of data to store it.

    With that much capacity, maybe we can get higher than full HD video and lossless surround sound audio for the exact way it was recorded and meant to be heard in movies...

    but sadly this isn't targeted towards the media consumer...

    Although blu-ray has been taking off in the movie markets, for some reason, it's been struggling in standard data markets. I think that these new standards of blu-ray will appeal to more businesses that need to (or require to due to business standards) physically move data between media. Down with tape backups!

    I can't wait to see what the gaming industry will have in store for blu-ray when BD-ROMs become more standard in computers/laptops.

    I wonder how much will a game of this length cost?

    I don't think the human eye can tell the difference once you go beyond full HD unless your tv is 300 inches and you are watching it 10cm away.

    Like already mentioned here, the target is ... "primarily at commercial segments such as broadcasting, medical and document imaging enterprises with significant archiving needs."

    Which will not fly because there are other cheaper alternatives.

    Still cheaper and quicker to use external hard drives like others have said. The only BR drives I have are on my PS3's. I have a total of 6 discs, all of which cost me $5. Unless there are more good movies at that price I won't buy optical ever again. I almost never use CD's or DVD's anymore, and I used to go through thousands of blank DVD's a year.

    Are you being serious? My "Full HD" PC monitor isn't even half the size of my television, so I can definitely tell the difference when the image is stretched out an extra 40" or so. Maybe your eyes can't see beyond 1080p on a 50"-60" screen, but mine definitely can.

    Wasnt software the thing that wasnt keeping up with hardware. Now hardware is seriously outdating itself before many people get to experience it. I still dont have a BD Drive of any kind. Techs going too fast now.

    USB is the way to go. This blue ray is just silliness. hi speed SD cards and USB thumbdrives are the future.

    we were able to get by on a 100MB cart for the N64 and still pushed out a fair few lengthy titles, the major factor is rarely ever the size of the media but the dedication and skill of the development team, in fact if i were a betting man i think most devs aren't really coming close to using all of a standard blue ray disc effectively, mostly it's just HD cut scenes that eat up the space

    LTO 2 tape 200gb uncompressed - $22
    LTO 3 tape 400gb uncompressed - $23
    LTO 4 tape 800gb uncompressed - $29

    But the drive for those are really expensive so how about...

    2 TB external usb hard drive $159.

    The only person who would be interested in this bluray tech would be my last boss who wanted me to burn a terabyte of data onto standard CDs for a "backup" and refused to buy any other solution. Oh yeah He was Dutch too.

    It all depends on how far away you're sitting from the screen.

    My pc monitor is 26", and is 1920x1200. I sit about 1.5' away from my screen.

    My tv is 48", but i sit a good 3 metres away, so any increase in resolution wouldn't make a difference to me.

    Sure a 40" screen at a couple feet away will look awful at 1080p, but that isn't a realistic living room scenario, people sit 2 - 4 metres away from their tvs, so you need a massive screen to be able to discern the difference between image quality past 1080p.

    This is what wrw was talking about.

    For those poor innocent souls:

    More space will not bring more lenght to games. Most of supernes games have a lenght way beyond todays games.

    Even AAA games in this gen hardly surpass 6-8 hours of actual play unless is a adventure gamer(from nintendo most of the times), jrpg or western rpg. The rest just try to justify the minimal hous with "multiplayer" wich some people don't like.

    Wonder if the new standards will migrate from commercial use to personal use. Can't see it happening right now. Perhaps in the future.
