    Greater density on the same physical size is great (assuming reliability is not affected), but I'd really like to see affordable, large-capacity drives that can operate at very low/very high temperatures. Imagine the implications for portable/vehicular/MP3 type devices!

    The biggest problem with portable devices (like MP3 players) is that storage is so expensive, because leaving a conventional HDD in a cold car can demagnitize and permanently damage it.

      Huh? I know excessive heat can demagnetize, but excessive cold? IANAP, but I don't think so. At least not the kind of cold your car is likely to experience on the surface of the Earth...

      Anecdotal evidence: I left an IBM 20GB HDD in a car at -20C (that's about -5F, for the uncivilized) for several hours, and it's had no problems. Of course, maybe I was just lucky, but I've never heard anything before that suggested that cold could demagnetize something.

      Of course, cars can get very hot in the summer when parked in the sun, and portable MP3 players probably also take quite a beating. So I'd think heat and vibration would be the two big issues.

      I don't know how the heat issue could be avoided with a magnetic drive, except perhaps building a themos-like heat shield around the thing. I doubt that there exists any material that can remain magnetic at very high temperatures and which is also suitable for high-density data storage.

      I, my mother, my sister, and my father all regularly put our laptops (unless my sister steals mine to play Civ:CTP or HoMM3 or dad and I use his to look up flight charts) in the nose storage of a plane that flies at about 30,000 feet. No pressurization, no heat. And my laptop still works fine, thankee very much, sir (actually I'm looking at selling one of em if someone wants a TP 570 -- works great, almost new). I believe that heat is another matter, but I've had some laptops that get hot enough that the manual specifically states that you should never, ever put it on your lap (which is where I have it), and the hard drive works just fine.

      Another point is that this is self-assembling magnetic storage. I was at the last Foresight Convention on Nanotechnology, and for all the amazing and interesting things people had done or were trying to do, the real roadblock was self-assembly. building a motor with an AFM is not exactly practical.

      Offtopic: why can't we make players that read/write MD media, and play MP3's? Now that is something I would buy instantly. (or when I have enough PointClick dollars to get one -- really offtopic: why doesn't PointClick let you use Mozilla, dammit?)

    Well, maby not all.

    But just a reminder that IBM is a major producer of hard drive components, specificly the heads (which I would imagine are the hardest things to make).

    So even if you dont see drives around outside a big blue dominated envirment, IBM is major player in the storage business, for insanly large requirements (which we all know) and everywhere else too.

    And apparently they still have a nearly blank cheque research budget.

    1. Re:IBM stuff in all hard drives.. by Nagumo · · Score: 5

      The heads are a definitely an important product for IBM. And yes, you can find them in other vendor's products. As for the hardest part to make, perhaps, but there is another piece that is just as tough. The flex cable.

      Flex cable is the ribbon that connects the actuator to the electronics. Sounds easy, but you have to remember that this thing is moving (flexing) constantly. Back and forth, back and forth, back and forth, thousands and millions of times. It takes some serious physics to design these parts, while minimizing the costs. Constant movement inside a little oven, and you have to design these things to cost you pennies. Not easy.

      These are just two parts. What else is tough to make and requires significant engineering?

      • Platters which have to be ground super smooth and coated with the magnetic material. The slightest bump will cause all kinds of bad things to happen when the head contacts it.
      • The channel, which is essentially the A/D converter that takes the signal from the head. This is a big piece of R&D, and the specifics are highly guarded between HDD companies.
      • The interface code - controls how the drive interacts with the rest of the world. IDE, SCSI, FC-AL, etc. and of course it has to be tuned to handle the cases where the host adapter companies got the interface wrong.
      • the motor
      • Servo code to control the motor and the actuator. Handles the basics like seeking, and also the more advanced things like load/unload.
      • ESD concerns. The heads are extremely sensitive to static electricity. The electronics are too, but not to the same degree.
      • Electronic board layout. This is a lot of tradeoffs to cut cost.
      • Power and heat concerns. The attention that these two items get is psychotic. The drives today are very efficient machines.
      • Test. Especially when working with the newer interfaces, newer heads (ie. GMR), etc. Lots of work here. The absolutely worst thing a drive can do is return incorrect data and declare it to be correct. Slightly less severe than this is if the drive explodes in a giant fireball. (At least then you know the data is bad.)

      This is just what I can come up with off the top of my head. The HDD world is a great mix of software and hardware (and some really genius R&D people). The cost to enter this market is absolutely enormous. And to remain in the lead requires a constant investment.

    In 3001, Arthur C. Clarke predicts that the maximum amount of data we'll ever be able to get on a device about the size of today's zip disks is about a petabyte (=1000 terabytes), a staggering amount of information. With this it would appear that we're getting one step closer to this limit, or at least *a* limit. It will be interesting to see what the actual maximum data density storage is... it might even get as far as using the orientation of quarks to store the data. With this then you could store the majority of the world's knowledge (if not all) in a canister of oxygen, or a jug of water.

    However, it seems that the more storage we invent, the more we need so in that jug of water all you would probaly fit would be Windows3000. The real problem isn't being addressed here: how to use the storage we have efficiently rather than how to invent more to waste.

    And right now that seems to be the biggest problem they face with this technology, too.

    From my point of view, the most interesting thing about this development (and one of the least commented-on, for some reason) is the fact that they're using bottom-up assembly for the recording medium, instead of a top-down process like almost everything else has required. This is a ground-breaking development in the nanotechnology field: instead of using an atomic force microscope to drag atoms into place, they're growing the magnetic domains in their final, self-organized locations.

    This is great stuff!
