Holographic Storage Crams in 0.5TB Per Square Inch

      Your question is really backwards ; the idea of writing the same data to two or three places is just a very crude form of the "normal error correction" you refer to. "normal error correction" on CDs is implemented by cross-interleaved Reed-Solomon data encoding. It is far far more efficient than simply duplicating the data several times.

      If you can describe the error model of the medium, that is what types of errors are likely to occur (random dropouts, scratches which cause burst errors), you can then lay out the data on the disk to convert the statistically most likely errors into error distributions that your error correcting code is most able to deal with. For example, the Reed Solomon code deals with random errors the best, so you use two dimensional interleaving to convert burst errors (caused by scratches) into random errors sprinkled over many code words.

      The Reed Solomon code can correct an unbelievable number of errors, it is almost perfect. If you have 2N parity bytes, it can correct N random errors or up to 2N "erasures" (errors where you know the location of the error, due to the underlying demodulator telling you something is fucked).

      So if you naively just duplicate 100 Gigabytes data three times, you've got 300 GB but then you're screwed if two bytes of that data are corrupted in the different copies. If you use Reed Solomon, you would only need two extra bytes to give you the same protection.

    I think it's just the new higher 'resolution' technology that's presently limited to 20MB/s.

    The older stuff that got something like 200G/in^2 had a much faster transfer rate, but lower density.

    It's all due to the electronic end, really. The laser picks up the data at 1G/s, but the electronics take much longer to send it out to whatever bus reads it.

  37. I'm very worried about large, cheap data storage by DigiShaman · · Score: 4, Interesting

    As the subject line says, I'm very very worried. I mean this from a "1984" standpoint.

    We've already read stories about how our past activities on the Internet (news groups, blogs...etc) can catch up with our future in a very bad way. With storage getting cheap and more abundant, I fear that giant archives of public data will be collected daily and stored for hundreds of years...all ready to be pulled for review later. Any place, at any moment, digital video of you recorded in public can be data-mined using facial feature algorithms to track your history of where you went, when, and for how long.

    While such technology will certainly be available in the UK, there is nothing against US law from preventing it happening here. Homeland Security, Patriot Act...bla bla bla. It's just a matter of time when terabytes are cents on the dollar.

  41. Some concerns... by jtcedinburgh · · Score: 2, Insightful

    My worry about all this ever increasing storage capacity is the fact that affordable, non-disk based backup systems don't appear to be evolving at the same rate. So, we're in a situation that a full disk backup might span 100 dual layer DVDs, which is a hell of an undertaking. Sure, Blu-Ray and HD DVD might help, but at best estimates they're still lagging a long way back.

    As we start using and creating more and more media rich content on our machines, it's going to start getting *very* tricky to ensure that content is backed up, and I suspect a lot of us simply won't bother.

    Also, doesn't packing higher densities of data together make it more prone to corruption/problems, and even if it isn't more prone, surely we're going to end up with incredibly large 'baskets' into which we place all of our valuable 'eggs'?

    Someone correct me if I'm wrong, but it's something I've been worried about for some time - and having a machine with ~700Gb storage at present (most of that free space for now) I worry about how I can safely back this stuff up without buying yet another hard disk. I prefer to spread my risk over different media types - CD/DVD/Hard Disks/Online Solutions - but other than big hard disks, none of the others have evolved anywhere near quickly enough to accommodate these huge capacity drives...

  42. Re:But it moooves by donaldm · · Score: 2, Interesting

    Well I sort of agree with you about solid state storage but there are a few flaws in your logic.

    I will answer with a question. Why do people or organisations backup their data?

    Most PC uses may backup their data to floppy (now obsolete) or to zip (getting obsolete) or CD or DVD but rarely to tape because it is not cheap and it is inconvenient.

    Most organisation backup their data (from a few 10's of GB to 1000's of TB) mainly with tape devices (super DLT's can save approx 400 to 600 GB per tape) with approx 50MB/sec through put. This solution can be very expensive ($10k to $100M). Solid state storage can do this but the cost would get quite expensive. Even disk storage would be cheaper than solid state however any company that wants to stay in business should have a Disaster Recovery Program for their IT department and this means off-site storage of backup media.

    Government organisation (ie. Tax Department) require data retention for seven years and some even longer. Now solid state and even disk backups become so expensive you need to have the budget of NASA for even a small company. If the company requires off-site backups then at the moment tapes are the only solution.

    What is important here is the potential of the Holographic Versatile Disk (HVD). They are starting with 300GB @ 20MB/sec and assuming the writers/readers are say $2k each (guessing here but reasonable) you could get a multi-stacker silo (say 6 heads and 50 disks) for say $20k that would have a through-put of 120MB/s which would be fine for small to medium sized companies. An equivalent tape machine would cost close to $50 and up depending on your tape silo and not only would it would be much larger it would have a slower response for the robot stacker.

    Assuming a HVD multi-stacker library of similar performance to it's tape/cartridge equivalent the overall cost now comes down to the media and I am quite sure HVD disks will be at least 10 to 20 times cheaper than the equivalent tape/cartridge. Coupled with that will be the potential longer life and small storage area of the HVD, not to mention "near-line recovery" capabilities.

    What we are seeing with HVD is a change away from tape backup units and anyone who has worked in this area will welcome that.

    On an interesting note. It looks like the VHS tape recorders are being phased out by HD and/or DVD recorders. I am sure the same will happen when HVD are pushed as the new backup strategy. Think thin DVD's (even in a protective case) compared to bulky VHS cassettes.

    Note: You should not compare CD's, DVD, HD-DVD and BluRay with HVD since they are aimed at different areas of IT, however that is a subject for another day.
