GE Bets On Holographic Optical Storage 159

Lucas123 writes "Years after announcing they had developed holographic optical disc technology that could store 500GB of data, GE this week said they're preparing to license the technology to manufacturing partners. At the same time, InPhase, which failed to actually get its holographic disc product out the door for years, says GE's product is nothing more than a 'science project,' and its own optical disc is almost ready to go to market — again. But, as one analyst quipped, the old joke about optical disc is that 'there's more written about optical disc than stored on it.'"

      That means that hardware will be in production and quite probably in place before the media groups start to even think about their next DRM / license encrusted format.

      Work began on the next-generation codec in 2004:

      HEVC aims to substantially improve coding efficiency compared to AVC High Profile, i.e. reduce bitrate requirements by half with comparable image quality, probably at the expense of increased computational complexity. Depending on the application requirements, HEVC should be able to trade off computational complexity, compression rate, robustness to errors and processing delay time.

      HEVC is targeted at next-generation HDTV displays and content capture systems which feature progressive scanned frame rates and display resolutions from QVGA (320x240) up to 1080p and Ultra HDTV (7680x4320), as well as improved picture quality in terms of noise level, color gamut and dynamic range.

      The timescale for completing the HEVC standard is as follows:

      February 2012: Committee Draft (complete draft of standard)
      July 2012: Draft International Standard
      January 2013: Final Draft International Standard (ready to be ratified as a Standard)

      • Optical media has a couple things going for it over tape:

        The media is composed of 20 stacked layers of 25GB each. It is conceivable that with sufficient focusing, they can simply continue stacking layers as needed.

        Despite images floating around the internet, optical disks can be accessed randomly, and there is no need for a 'DVD Rewinder'. You don't need to spend time spooling to the specific location you need before you can read the data.

Personally I think it's DOA. Magnetic HDs are super cheap and SSDs are super fast, durable and are very versatile. I'm just not sure where the demand will come from for optical HDs. Any ideas?

          • Sounds like it would be useful to store OS & programs for a kiosk based computer. Plenty of space. (presumably) cheaper than a magnetic drive. And (presumably) read-only media could actually be a plus.

        • While I agree with you completely, you would only need relative cheap carousel loaders, not the big robotic loaders you see on tape archives. Sony makes a handful of them for DVDs that store between 200 and 400 disks, around a central reader.

By the time they get this to market everything will be solid state and/or in the cloud. Oh well, I was excited about these high capacity optical disks five to ten years ago. Now I just feel bad someone's wasting their r&d time and money on it.

      • If you re-read my comment, you'll notice I made a point to mention local storage too. I do not believe the cloud will completely replace local storage in the foreseeable future, but by the time these optical disks get to market something like a 500GB USB3 thumb drive will be commonplace and will most likely outperform them in speed, price, and reliability.

      • The advantage of optical disks is that they are cheap and easy to post. If (and that's a big 'if') 500GB disks can be made cheaply, then you can just burn one and pop it in the post every week, and you've got off-site backups for the cost of one stamp. If you need them back, first class post will get them returned to you the next day, very cheaply.

          • Try posting a 500GB hard drive every week, then try posting a CD-sized letter every week, and see what the difference is. Aside from cost, there's also the fact that the letter will be slipped through the letter box without any problems, while the hard disk needs someone in to receive it.

            • Everywhere I've ever worked that was big enough to want offsite data storage, there's been a shipping/receiver position. Cost? Maybe $100/yr. Not enough to be meaningful.

For a home user, popping an optical disk in the post is much cheaper than shipping a hard drive. Especially if you're posting them to a relative who doesn't live nearby, because then you can use the cheaper WORM disks and not need to worry about getting them back unless you have to do a restore.

      Except what they are talking about is not your typical old opitical disk technology. They are basically talking about storing data in a 3 dimensional photosensitive material. I read an article in Wired a while back that was talking about something like a 500GB capacity in a 1cm square block I believe. Its much more efficient than magnetic storage, and more resilient than non-volitile solid state storage. The technology holds a lot of promise I think if they can make it affordable. GE is appears to be intent on preparing it in a disc configuration, but if this technolgy becomes readily available I would imagine we might start seeing things like the crystals in Supermans fortress of solitude with terabytes of capacity. I really dont understand enough about the technology to speak on its limitations and roadblocks, but the possibilities are fascinating to say the least.
