InPhase Technologies Promises Holographic Drive in May 194

Anonymous Coward writes "After 8 years of effort, InPhase Technologies is shipping the world's first holographic disk drive next month. They showed it at this week's NAB. With a 300GB 5.25" disk cartridge and a 50-year media life, the Tapestry 300r is aimed at the video and film archive market. They've been promising this thing for so long I'd given up hope that they'd ever ship it!"

    I've dreamed often of the day I could buy a completely non-standard technology that rids me of large quantities of the pesky money I have lying around while at the same time solves the removable storage problems of 3 years ago. Too bad this unit only costs $18,000 and stores just under 1/3 of my hard disk space!
    • Exactly. You can get a 500 GB hard disk for $100. Why not just use those for backup. At the cost of this holographic storage, you could buy 2 or 3 500 GB hard drives, and keep multiple copies just in case one died. Since you'd only be using them for backup, and they would actually get very little wear and tear, I would guess that it would be easy to have a hard drive last for 50 years.

        Heck, wait 3 years and you'll be able to buy 500 gig usb keys for $100. You can buy an 8 gig kensington USB drive for $30 right now ... they were $120 a year ago. If capacity continues to quadruple every year for the same price point, you're looking at 32 gig for $30 next year, or +/-$100 for 100 gig, 400 gig in 2 years, and a terabyte in 3-1/2. Of course, by then, you'll be able to buy 2TB hard drives for $50 ...

        Because it violates a fundamental IT principle: always keep your backup media separate from your reader. With a 500GB HDD, your reader and your media are the same thing.

        Keeping media and reader separate helps to protect against total catastrophe.

    I can see a hundred posts from people that will completely miss the point. All because of the price. Bitch, Moan, Bitch, Bitch, Moan, Moan.

    FTA:

    Holographic storage has a couple of neat properties.
     
    1. A small fragment of a hologram can reconstruct the entire data image. The fragment won't let you move as far around the image, but for 2D images, like a photograph, it means a scratch isn't fatal.
    2. Data density is theoretically unlimited. By varying the angle between the reference and illumination beams - or the angle of the media - hundreds of holograms can be stored in the same physical area.
     
    Another factor: photographic media has the longest proven lifespan - over a century - of any modern media. Since there's no physical contact you can read the media millions of times with no degradation.
     
    They've spec'd the optical media they use - a 5.25 clear disk in a cartridge - at 50 years.


    Spinning Hard drives, Solid State Hard drives, CD's, and DVD's don't have anything CLOSE to holographic media.

    Spinning Hard drives could be used, and they are, to store data for long periods of time. Problem is that it susceptible to EM fields and even while not spinning, it might be possible to have some degradation nonetheless. Holographic media is not affected by EM fields.

    Solid State Hard drives are better off than spinning ones for sure, but still suffer from the same problems with an EM field AFAIK.

    CD's and DVD's long shelf life is a MYTH. Most of them are not manufactured to last longer then 5-10 years. A scratch can easily damage either one of them, and repairs are not easy. Holographic Medium? Apparently not.

    So the .50 cent per gigabyte price point may not be that attractive to the average IT guy, but when you have to make ABSOLUTELY sure the data will remain intact it certainly sounds like the way to go. The 18,000$ dollar cost for reader/writer will come down eventually, so that is really not even an issue. Hell, my first CD-R cost me 600$ and I STILL have my 1200$ Pinnacle Micro 4x4.

    The fact they actually got it to production and selling it means there is a pretty good chance of seeing a few thousand dollar reader/writer within 2 years.

    For those that are really hung up on the price, consider this:

    To be REALLY safe with your data you would have remove all single points of failure. A single hard drive on a shelf IS a single point of failure, as is a CD/DVD. So you would need to be constantly "rolling" over the data in multiple RAIDS with snapshots, while at the same time, verifying the integrity with checksums before every snapshot. To take it one step further, multiple locations that synchronize over high speed networks... iSCSI?

    Apparently a holographic medium can be written with "hundreds of holograms being stored in the same physical area". Sure sounds to me like you could store quite a bit of data with a considerable amount of recovery capability. I would hazard a guess, that just a few of these written this way and stored in separate physical locations would provide the same level of reliability and redundancy that current solutions provide (such as the one I outlined)... with a 50-100 year shelf life. If you look up the actual costs of iSCSI this sounds like a bargain to me.

        Who is to say that they will not license the technology? If they go out of business, somebody stepped into to buy the assets. Technology patented? Patents disappear in 20 years (or they should).

        How is the reader susceptible to magnetic fields again? We are talking about just the reader right? If you are referring to EMP blasts from something like a nuclear device, then the fact your holo reader is not working is the least of your problems. Not trying to be sarcastic (at least not totally), but how does EM affect any kind of CD/DVD/HOLO readers?

        You are also forgetting the target market here. Somebody like Disney. Didn't we just hear that a FUCKING JANITOR found one of Disney's long lost films in Japan? When you have incredibly valuable content that you have created, and archiving process like this is well worth it. If they don't have working readers in 40 years, I would say they could afford to have a firm make one for them from the plans available on the Internet in 2058.

        The technology itself is promising, and "lots of standard HD's" are not a better option, or safer. If you were to evaluate the total costs, standard HD's would cost your more in the long run to achieve the same level of reliability as this holographic technology.

        You also need to remember, this is not like a hard drive. It does not have any proprietary IC components, no internal firmwares, no connectors, moving parts, etc. It is a solid piece of holographic material. If you take it out of the case and set it on a desk, you can SEE the data with your own eyes. To get the data back off into a computer system, simply requires some lasers and mathematical algorithms, which I would guess is going to be trivial in a few decades. A hard drive is NOT the same. If you took a 250 MEG HD from over 15 years ago and had to remove the platters, just how easy would it be to find parts that could read those platters again? Remember, the density has changed from 15 years ago. The internal parts and technology in hard drives is substantially different now. At least with Holographic media, you don't even have to TOUCH it. Just set it on top of some lasers and read it with whatever technology you have.

          If you're Disney, or anyone else with data valuable enough to possibly justify recreating an ancient media format reader, then the correct archive solution isn't a single format. It's a storage facility that has people maintaining the archive and updating formats and verifying that the data is still readable. Rather like a library, complete with librarians.

          If you're comparing reconstructing a reader, then reading an ancient 250MB disk is easy -- there is tech now that can read off damaged and warped platters through techniques not dissimilar to electron microscopy, and I guarantee it could handle a far-less-dense 250MB drive without issue. Figuring out the low-level formatting would be no harder than for the holo media, and probably rather easier.

      A scratch loses you data, period. Whether it's holographic or not, you're either trading capacity for recoverability or you're vulnerable to a scratch. There's no magic here. Even with Blu-Ray you could store the data using forward error correction in such a way that complete obliteration of 1/4 of the disc still yields 100% of your data-- you'll just reduce the storage capacity somewhat.

      Presumably, however, holographic storage has so much dang storage available that it's not a problem to give some of it up to have enough redundancy to survive typical wear and tear. (And all optical media gets wear and tear just from being spun up and down in non-cleanroom environments.)

      And if you're worried about the longevity of CDs and DVDs, scratches aren't really what you're worried about anyway. Most scratches are on the clear plastic and can be repaired. However, some discs were manufactured with chemicals that oxidizes the layers, some with defects in the seal, etc. So your typical "stamped" disc will last decades if free of defect, but less than a decade if it has one-- and there's almost no way of knowing ahead of time. I don't know what substrate the holographic image is being stored on, but we'll have to see if it's completely free of degradation over decades. I certainly wouldn't want to immediately dump important data into this format and throw away the originals yet.

      So for now it just remains an expensive unproven alternative... we'll have to see where it goes, though.

        Not exactly. As I understand it holographic media works fundamentally different from an optical disk and no bit is dependent on a single location on the disk. Instead of a scratch taking out several bits from different tracks that the CRC codes make up for a scratch makes a large number of bits loose definition uncritically. In this fashion a holographic disk would take quite a few scratches with no data lost until it started reaching a threshold where all of the bits started to read unreliably all at once. That said I'm coming from Wikipedia so who knows how biased and inaccurate that information is for this particular technology.

          If they're doing a spinning media with serial read and write patterns, that implies that the size of the coherent hologram is vastly less than the size of the disk. Which means that scratches lose the data that is stored on that part of the disk. I have no idea how large a domain they're using, but I'd guess kilobits or less.

      Huh? The theoretical possibilities aren't important -- what matters is what this drive can do, at least when you start talking about price. Physical holograms can no more hold infinite data than analog film has infinite resolution -- there are limitations somewhere, be they high or low. If you push close to those limitations, it won't be scratch resistant -- how resistant it is to damage depends on how much error correction you have, be it in the form of not using the full available resolution or by using electronic ECC techniques. (Care to guess which one is more efficient? Care to guess which one CDs and DVDs use?)

      As for longevity -- there's no particular reason the plastics in the holographic storage will have any longer life than CDs or DVDs. If they say it'll last 50 years, then I'm inclined to believe they used decent plastics. But, you can get CD / DVD media that's rated for 300 years. It doesn't matter what damage sources holograms are "theoretically" susceptible to, what matters is what *this product* is susceptible to. Perhaps it doesn't delaminate, but what about heat / humidity / CD eating bacteria [bbc.co.uk]?

      For archival media, my biggest concern would be whether I can find a reader in 50 years. I think the odds of that are a lot better for CD / DVD than for this -- though if I really care, it definitely needs some sort of maintenance program to make sure the data is intact and readable.

Sure, if by "proven" you mean look at all those photos I print that are already fading. Oh, you mean those old chemical and film photos?

And CDs lets not forget. Teh lazers! They rulz?

And then forget about it! By the magic of holo storage, whatever you had meant to put on the disk will eventually be there. Along with the stuff you actually put there. And the fixed up and corrected versions of both of those. And the one where your spelling typos have been fixed up, and your girlfriend's photo looks like (oh, wait, no gf? nevermind then.).

      Solid State Hard drives are better off than spinning ones for sure, but still suffer from the same problems with an EM field AFAIK.

      This is not quite correct. Sure, if you zap them with a large enough static charge it will burn out the chips - but this is more likely to apply to the interface chips rather than the flash that carries data. Flash is also susceptible to radiation. Otherwise it is pretty robust.

As a side note, stamped media looks to do much better than burned media and last much longer than 10 years. In the end I wouldn't trust any one media, the only salvation is parity and redundancy as the holographic discs could be physically destroyed too.

But even the well made stuff barely lasts 1/3 the time.

      To be REALLY safe with your data you would have remove all single points of failure. A single hard drive on a shelf IS a single point of failure, as is a CD/DVD. So you would need to be constantly "rolling" over the data in multiple RAIDS with snapshots, while at the same time, verifying the integrity with checksums before every snapshot. To take it one step further, multiple locations that synchronize over high speed networks... iSCSI?

      That's exactly the thing. Multiple HDs are by far the cheapest way to store data and can be as safe as anything else, but it's really an active storage method. It's only safe if the drives spin up from time to time, get re-verified and replaced every few years (failed or not).

      What's really desired is a more passive archival system. Write it here (with a copy here) and put it on a shelf somewhere. In 50 years blow the dust off and read it back.

    Their main selling point is longevity. You can store the data on a disk and read it back 50 years from now. Will this company even exist 50 years from now? Will anyone have the equipment to read one of these disks in 50 years? Have they published the specs so you can construct your own equipment, should it become necessary? I don't see this working out. Archiving needs to be done with well-known open standards. InPhase doesn't seem to be off to a very good start in that respect.

    - We were also told CD and DVD storage was long lived. While 30 years can be expected of a few of the highest grade disks http://club.cdfreaks.com/f33/taiyo-yuden-faq-178622/ [cdfreaks.com] 3 years is what most of them manage. Theoretical limits typically don't make it past manufacturers.

    - It may indeed last 50 years, but will the equipment it's to be connected to? I've got the first 100MB drive to hit the market. It has lots of stuff on it I want to retrieve. It's a good thing I've kept the 18 year old Apple IIgs it's inside of operating.

    Better implemented on solid state holographic storage, but still possible on disk, is the reverse processing of image to beams. (There's a SciAm article from 1995 or so on holographic storage, particularly solid state, that covers this).

    Store lots of images on the disk. Illuminate it with a hologram of a target image. Out of each image comes copies of the original reference beams, at a strength proportional to the similarity of the stored image to the target image. Nearly instantaneous, simultaneous retrieval with correlation score built into the signal strength. Lost is the different angles that'd be had in a solid state device, so scanning the disk for reading all the beams and finding those of interest might take a bit longer. The entire US government fingerprint files could fit on one disk and the whole thing searched in seconds, as is often seen on TV. Using it for movie storage makes marketing sense, especially with the initial price tag of $18,000 and disks being $180. But leaving it at that would be a damn shame.

    Holographic technology turned into a functioning read/write data system? --Just the idea is SO totally cool! The linear storage we've seen to date has been like the Formula One race track of development, and people have come up with some very clever techniques to squeeze every scrap of use out of it, but really, we've been locked in two dimensions for all this time. Adding a third dimension is watershed stuff. Talk about blasting Moore's Law out of orbit!

    Think about those early 10 megabyte hard drives. Take that form factor and blow it up over the same length of time and you get some crazy-huge numbers. A third dimension to play with? That's like going from DC to AC in terms of complexity and possibility. Interestingly enough, the establishment resisted AC as well. I half suspect that the math simply demanded more brain power than the old school engineers were willing or able to invest.

    I remember the day when a roommate took the indoor cat out to the roof. The cat saw the sky for the first time and wet itself, flattened right to the ground and was basically reduced to a form of catatonia. After living in a one-floor apartment, (two-dimensional), being presented with a whole lot of up and down created a great deal of irritation.

    I remember hearing about the 4.6GB of storage back in the mid-90s, and it was quite underwhelming when it came out. MO never really took off, long-term. This, I think, may be different.

    If the technology in this stuff pans out and can be developed economically and scale well over time (MO didn't), I think it has some real opportunities to take off in certain sectors. It's not for everyone, but neither are rackmounted RAIDs, iSCSI and tape loaders.

    For naysayers: do any of you think that this company WANTS to release a boat anchor device like it seems to be going by their pictures? If what the company says is true, and this is not vaporware, the physical size of the drive may be a worthwhile trade-off in terms of capacity and reliability. As technology is developed, processes shrink, things get cheaper, and storage capacity gets bigger. I remember old MO drives being big, and as some pointed, out, a single CD-R costing $40.

    I'm not going to buy this thing, but I'll certainly be watching its development in the marketplace. It's interesting to watch, just like I did the Apex back in the day.

    It's really embarassingly bad. It makes 2 claims:

          1. A small fragment of a hologram can reconstruct the entire data image. The fragment won't let you move as far around the image, but for 2D images, like a photograph, it means a scratch isn't fatal.

    This is complete nonsense. A fragment provides a *reduced quality* duplicate of the data image. This is not so bad for photographs, but for digital data it's critical. Bit basic information theory says you can't recover the full image without actually storing the full image.

          2. Data density is theoretically unlimited. By varying the angle between the reference and illumination beams - or the angle of the media - hundreds of holograms can be stored in the same physical area.

    Again, complete horse hockey pucks. Storage of additional images on a physical medium is certainly possible, but the ability to control the aforesaid 'angle' and recover meaningful data is not infinite. It's limited by the theoretical factors like optical diffraction and resolution, and by the spatial resolution of normal matter made up of real molecules.

      You missed one, dude:

      3) No degradation while reading. While this may be true of familiar types of holograms, it is most certainly not true of read/write holographic materials. In fact, degradation of signal during read is one of the biggest problems that held this technology back for so many years.
      • Good point. That's a subtlety of the particular technology, though. It's not a basic violation of the laws of physics to claim it's true for this approach, unlike the claims of infinite storage and no data loss from corrupting part of the media.
