50th Anniversary of the First Hard Drive 225

Posted by Zonk from the whirrr-click dept.
ennuiner writes "Over at Newsweek Steven Levy has a column commemorating IBM's introduction of the first hard drive 50 years ago. The drive was the size of two refrigerators, weighed a ton, and had a vast 5MB capacity. They also discuss the future of data storage." From the article: "Experts agree that the amazing gains in storage density at low cost will continue for at least the next couple of decades, allowing cheap peta-bytes (millions of gigabytes) of storage to corporations and terabytes (thousands of gigs) to the home. Meanwhile, drives with mere hundreds of gigabytes will be small enough to wear as jewelry."

        That isn't true in my experience. Every hard drive I purchase gets harder and harder to fill up. Remember back in the DOS days? I do. My first HD was 40 megs. I was ALWAYS backing up to floppies. Not out of fear the drive would die, but because I was always having to move things on and off the HD to because of the limited space. That problem has been less and less severe over the years. HDs, for me, are rising in size faster than I can change my data downloading habits to keep them full. That may or may not always be true, but I'm drawing from over 10 years of computing here.

      Exactly. I'm wondering who these experts are anyways as we're about to hit a major wall in the next decade. We've been reducing the spacing between the transducer (read-write element) and magnetic media in HDD for about 50 years now. Each year the transducer gets closer to the disk and, as a result, storage densities have been going up. However, within a few years, we won't be able to get closer without having to worry about intermolecular forces [wikipedia.org] that come into play at spacings below 5nm. These can cause serious flying problems for a slider in a hard disk drive.

      To get closer to the disk, many researchers are looking at actually running a disk with the slider in contact with the disk. From a mechanics standpoint, that's just frightening. When you think about the friction and wear this will cause on the nanometer thin films on a disk platter, the outlook it isn't all that good...

      Now I will say that people have been predicting the demise of the hard disk drive for decades. For example, they never thought it would be possible to fly a slider at spacings less than the mean free path of air (~65nm) but HDD sliders currently fly with a minimum spacing of about 7-12nm. HDD Engineers have been able to overcome every major technical of the last 50 years and have, so far, won the cost per GB storage war. Even so, I'm curious how they'll get over the hurdles of the next decade as they're looking pretty frightening.

In any case, if we actually get the physical bits down to atomic sizes, even in 2D it'd be pretty immense. Can someone do a back of the napkin calculation for this?

      Probably the same day, or at least the same week. The disk platters were open to the air, and the read-write head "flew" a few micrometers above the disk surface, kept apart only by the cushioning effect of the air. If a speck of dust got between the head and the platter, the head would crash into the platter like an airplane that had lost its wings. Probably where our notion of "system crash" comes from, come to think of it.

      Well, let's see... apologies in advance for getting the numbers wrong, I always mess up my conversions (but it doesn't matter as you'll see at the end).
      But 5 Mb = 5 242 880 bytes = 41 943 040 bits (that is assuming I got it right)

      Now, I don't know exactly what sort of resolution you had on punch cards, but it's probably fair to assume that, including padding, a centimeter squared would do per bit. so you need 41 943 040 cm^2 = 4 194.304 square meters of punch cards. Now say, just for the sake of the argument, that your punch cards are 30x 30 = 900cm^2, you would need 46 603.3777.... of them. And then it all boils down to how thin your punch cards can be, but just intuitively, I'd say, yeah, you can easily fill up that space with 5Mb worth of punch cards.

      But then again, you are missing the entire point. Punch cards are not rewritable, hard disks are and that is the innovative bit. So it doesn't matter whether or not you can put punch cards in that space, it's all about being able to reuse said space.
      • The most common format of punch cards had 80 columns of 12 holes... and a surface area of about 155cm^2, and a thickness of 0.018cm, giving a bit density of about 345bits per cm^3

Then we have 10^-2 / 10 ^ 6 = 10^-8 m to be the length/width of a bit. A hydrogen atom is ~ 10^-10m (I think Iron is ~2.5 times that size). So roughly, bits would be a maximum of 100 x 100 atoms, but probably more towards 50 x 50.

The storage unit is "the size of two refrigerators" or (my guess) 5' wide by 6' high by 3' deep or 5*6*3 = 90 cubic feet or 90*12e3 = 155520 cubic inches. 155530 / 5*10e7 = 1/321. Therefore the 50-year old drive had (very approximately) an average of 321 bits per cubic inch. .wk.
    • I was just curious about how big a bit is going to be on these new drives

      If the bit is vertical I guess that would mean taller hard drives, thus causing computer cases to get bigger. This is an obvious indicator of waste and largesse in modern western societies.

    Oh hard drives how you curse me.

    I love these things and I hate them, as an enthusiast I've always been a big fan of the high performance hard disk. I've done my best to learn about them, I've theorised about ways of speeding them up, I've discussed the technology with friends for hours at a time in a geek like fasion.

    As much as I love a fast hard disk and I love a big hard disk I also hate these hard disks, because ultimately it's a very old fasioned method of storing our data, it's just some magnetic disc spinning same as it did 50 years ago.

    When you really think about it, it's just a really extreme tape drive with better random access, there's moving parts, it's delicate, they can run hot, they can be noisy etc.

    I recall my C64 as a boy, sure it had that weird "computer high pitch whine" to it but when the 1541-II wasn't reading data that baby was pretty damn quiet, I miss those days and hard disks don't help.

    What we need is to finally see the end of the hard disk, some new method of storing data, something which holds more, reads and writes faster, less delicate and no moving parts - of course solid state sucks right now but damnit I recall discussing holographic drives storing data on a small cube the size of a peice of sugar at 2tb or something (so the rumours went, like 5 or 10 years ago)

    The oven had the microwave replace it with a whole new tech, the television had the LCD / plasma, sending data has gone (at points) from copper to light - cmon where's the magnetic storage replacement, something to put us in the 21'st century?

    So in conclusion, I love them but I also hate them - it's really time for something new,...

      It's like you're saying your Honda Accord needs to be replaced by some new technology because it's the same thing as a Model T. It's obviously not. And the technology nor infrastructure does not yet exist to efficiently replace it.

      The same concept applies here. We'll have something "new" as you say when the technology is available at a reasonable price.
      • I realise that nothing is out there yet which can replace it, that doesn't stop one hoping, especially with every couple of years an "amazing new technology" being announced but never making it to market.

        The other problem is, right now if "they" released something which was bigger, faster, lighter, quieter than hard disks, it would either cost a boatload and fail or if it was priced correctly - destroy the hard disk industry as we know it over night.

      I think it's too soon to expect something to change just because it's now the "21st Century". There are alternatives if you are serious enough about using them, but the reality is that you must resign yourself to the fact that it is the best tool for the job. If there was something else that was more economical, then it would probably be in dominant use. Frankly, hard drives work well enough, IMO, and have an unbeatable value in cost, number of re-writes and capacity. I

    All this new storage space will doubtless be quite useful, but I wonder if we're about to get to the point where the network becomes the primary limiting factor in the usefuless of a computer (for most users), rather than the size of the hard drive? Just as memory is now usually the bottleneck, rather than the CPU, I can see that very soon the extra space will exceed that which can be downloaded in a reasonable amount of time (say, a year) - especially in sprawling, predominantly rural countries like the US.

    I've played around with the notion of there being "content neutral" downloading services, where people bring in their external hard drives, plug in, and download at very high speeds for a premium, returning in an hour or so (akin to having film developed). This may actually make sense at some point, provided the legal hurdles can be jumped.
  • The company I worked for while I was in college in the early '80's had my first encounters with hard drives: removable 52MB multi-platter packs in a washing-machine-sized enclosure.

    In '84 at my next job, the Lisa HDD was 5MB for either $1500 or $2500, I don't remember exactly. I remember the first hard drives for the Mac whose controllers clipped onto the CPU, and I think ran around $1000 for $20.

    I finally cracked down and bought a 20MB drive for a Mac Plus for $600 -- that was a bargain.

    I worked with similar large drives described in the article. They were CDC's first drives. The heads were moved by hydraulics and the tracks (cylinders) were counted by an etched opticial disk read by a photocell. Once the head was "on track" then a solenoid would drop a detent pawl into a square toothed gear to hold it on track. All mechanical. No voice coil to move the heads just the hydraulics.

    Each disk drive was about the size of a large computer desk and had a capacity of 262KB which is not very much compared with today's disk drives. But compared to a hollerith card it was a lot of storage when comparing to the 80 bytes or even a deck of cards. The operating system at the time was 2K in size which was one box of cards and could easily be contained on the disk drive platter.

    By keying in the bootstrap program at the console and pressing "run" then the system would read from a particular location on the disk drive which was the location of the operating system. The program would then execute the code in core and thus the system was up and running.

    The worst failure would be a ruptured hydraulic hose spewing hydraulic fluid over the entire guts of the machine. Difficult to clean up... difficult to hold onto slippery parts... and difficult to repair.

    There was only limited electronics in the disk drive itself. The controller was a refrigerator size box that held each gate on a separate circuit board. These were troubleshot utilizing a oscilloscope on a cart so it could be moved about. Each input to a gate had a test point and the output(s) also had test points. Each gate (like and, nor etc) was an individual small PC board so a disk controller might have 600 boards in it. One needed to be totally aware of each circuit and how it worked and what the signal at each junction was to be. No board swapping here. One had to know or have a very good idea what the problem was before changing a board lest you have a contoller that is nearly unfixable in very short order.

    I was very skilled at repair and yet saw the writing on the wall even then as devices became smaller and "smart".

    No longer could one trace the signal from "turn on" button to spindle rotating through each stage and gate. Eventually the "start" button would signal the input to the processor aboard the disk drive and it would be the processor that commanded the spindle to start turning. At this stage troubleshooting became board swapping for the most part.

    That is when i moved from the technical hands on realm into programming.
