Table Salt Could Help Boost HDD Storage Density By a Factor of 5

hypnosec writes "A team of researchers has managed to boost storage density on traditional magnetic platters as high as 3.3 terabits per square inch using a technique that relies on NaCl — table salt. (Comparatively, a recent 4TB Seagate drive had an areal density of 625Gb per square inch.) A research team used a technique called nanopatterning to create arrays of magnetic bits that have more regular features (PDF) than the current traditional, randomly distributed technique. Team leader Joel Yang compares the technique to a well known traveling trick; 'It's like packing your clothes in your suitcase when you travel. The neater you pack them the more you can carry.' Yang said, 'In the same way, the team of scientists has used nanopatterning to closely pack more of the miniature structures that hold information in the form of bits, per unit area.'"

Metaphors

[uigrad_2000]

It's like packing your clothes in your suitcase when you travel. The neater you pack them the more you can carry.

Dr. Yang continued. "For speciality file systems, imagine you are travelling for a wedding, and you need to pack a suit. The extra meta data for the file system is stored in a container much like the suit compartment of your luggage."

Unfortunately, the metaphor did not stop there.

"Data read times have been improved also. Imagine again that the suitcase is packed neatly, but this time all clothes are on their sides. Now, imagine the suitcase is being spun in an x-ray device by the TSA. The tighter packing allows them to see more of what is packed in the suitcase during each arc of 30 degrees."

Re:Metaphors

[TheLink]

Seriously though, when I pack for travelling I roll up my clothes tightly but I don't twist them. That way they aren't really creased (in fact they are less creased than if I folded them "neatly")

Sometimes if I need more space I stuff the rolled up clothes in a plastic bag, and use a vacuum cleaner to suck some air out of the bag (to squeeze stuff more) - but you shouldn't do this if you might not have access to a vacuum cleaner for repacking and you won't have extra space (given away gifts, used consumables etc). Also be aware that the luggage compartments in many planes isn't pressurized so... ;)

Re:Metaphors

[PopeRatzo]

They used some crazy chemical here a couple years ago, it had a bluish tint.

Oh, that wasn't for the roads. It was actually a truckload of crystal meth that had somehow been fouled with VeryBerry Koolaid. Because of the ice on the roads, the 1993 Ford van that was carrying the meth skidded into a tree, popping the back doors open and spilling the meth all over the road.

A man driving a small SnowCat that was helping pull stranded motorists out of ditches on that stormy night happened to notice the meth spill and rushed to use the small backloader that he had mounted (poorly, because though he was a maker, he wasn't a very good one) on the front of the Cat to scoop up as much of the meth as possible so he could bring it back to his trailer, bag it up and along with his girlfriend, a night dispatcher at the local sheriff's department, sell it to high school kids and unemployed folks in the area. The unemployed folks were especially good customers, trading the balance on their food stamp cards for bags of meth.

So anyway, the guy driving the SnowCat sped back to his trailer and was too busy thinking about the new PS/3 and HighDef TV he was going to buy with the proceeds to notice that the wind was blowing most of the meth all over the road, spreading a thin layer of high-test speed throughout his route through the town. When he got home, he noticed the backloader was empty except for a little residue, which he quickly scraped up and smoked while he packed his bags for the trip he was going to take to Chicago, where he became a grad-student in English. He would later become a Professor of Literary Theory and bump into a young lecturer on campus who would later become President of the United States. Anyway, the local sheriff's office followed the trail of crystal meth to the man's trailer, but his (now ex-) girlfriend, who it turns out had been banging the chief deputy as well, intervened in order to keep the man's name (and hers) out of what would certainly be a big news story.

I know this all because...I am the man who was driving the SnowCat that night.

By the way, I know this is a little off-topic but that game, Rage? When I first played it, I was kind of disappointed because although the combat mechanics are pretty damn good, the game itself is just another post-apocalyptic romp with invisible walls where the developers don't want you to go. However (and this is really the point of my post) if you have a couple of glasses of nice vodka with blueberry juice the game is a fucking blast. But you have to drink enough so that you start to get that sort of echoey sound in your ears and your fingers start to feel a little tingly, right?

Anyway, I've got to get back to the game now. Have a good evening everyone.

[vencs]

Expected the TFA to have any detail about read/write speeds - something that one would expect about a HDD (not a lame suitcase analogy). Higher densities on platters often resulted in slower IO speeds as the heads proved not to be that precise in deciding whether a bit was set or not and so ends up in verifying the data using some ECC type mechanisms. May be the real motivation is to say that disk is the new tape.

Re:briny

[TheRaven64]

An increase in linear read speed, anyway. Hard drive random seek times haven't seen much change since the '80s. Densities have improved by a factor of over a million while seek times have improved by a factor of less than two.

Re:Important note:

Whenever the subject comes to data density I recall Heinlein take on this.

Basically you can take a match stick, and put a single mark on it. The distance between the mark and the end of the stick is the data being recorded. The higher precision the larger amount of data being recorded. With high enough precision a single mark could contain all the information that mankind has ever produced.

Re:Important note:

[interval1066]

Took me a minute becuase the article was very difficult for me to read (navy font against a lighter blue background, brilliant) but all they did was add table salt (in aqueous solution I'm sure) to the developing chemicals in the etching process. That's interesting from a chemistry persepective; it implies they may be able to even higher densities by fiddling around with that catalyst- in stead of salt maybe they add shrimp cocktail to the process and get peta byte capacities or something.

Re:Important note:

The information density is still limited by quantum gravity, which predicts discreteness of space-time at the Planck length scale.

Re:Important note:

That's not true. The number of marks you have after you write it is itself information. You'd be writing infinite data on a match stick!

No petabytes, because peta would object to the exploitation of shrimp.

Re:Important note:

If my math is right, Planck's length as your resolution limit gives you 6.187x10^34 possible marking positions per meter of stick, which means you can encode about 115 bits with one mark on a 1m Planck-grade stick.

Not quite. You can record one 115 bit value, which is very different from 115 bits. a 115 bit value has 2^115 = 42 million billion billion billion (10^34) bits of information.

A slight difference.

Re:Important note:

That depends on which definition of the word "areal" you use.

Re:Important note:

[JesseMcDonald]

You can record one 115 bit value, which is very different from 115 bits.

No, storing one arbitrary 115-bit value is exactly equal to storing 115 bits. The relationship is one-to-one:

8-bit value: 10110110 (181/255 ~= 0.713 units)
8 bits: 1 0 1 1 0 1 1 0

Re:Important note:

[artor3]

No, he had it right. There are ~6(10^34) = 2^115 marking positions. You mark one of them. That means you can select one value out of 2^115.

If I let you pick one value out of 2^10 = 1024, would you say that you have 10 bits of data or 1024 bits of data?

Or, to make it even easier, if I let you pick one value out of 2^0 = 1 (as in, you have to pick the number one and have no other option), is that zero bits of data or one?

Re:Important note:

[IorDMUX]

If I let you pick one value out of 2^10 = 1024, would you say that you have 10 bits of data or 1024 bits of data?

Well, actually, in my world of mixed signal and ADC design, we would refer to the resolution of the data as 10-bit. i.e. a 10 bit value. That 10 bit value can represent 1024 unique possibilities, or 1024 least-significant-bits (or, as we say, "bits") of data. For example, if our 10-bit ADC has 10 bits of error, then it is only a 1 % error.

Maybe it's an industry nomenclature thing. *shrug*

Thanks. My fingers nearly tripped and spelled 'Adobe' while trying to search what Qdoba was. Damned muscle memory dyslexia!!

Re:Important note:

[martin-boundary]

You're confused. 1024 possibilities is exactly the same as 10 yes/no questions. It takes 10 questions to find one value among 1024, using binary search.

So even though 2^115 is a big decimal number, that number represents only 115 independent yes/no questions. Or put another way: if you have 115 yes/no answers, and you want to represent them as a single symbol, then you'll need a huge number of symbols to handle all the possibilities, 2^115 different symbols, in fact.

Re:Important note:

[IorDMUX]

I believe I understand what you are saying... After all, your binary search is my successive approximation ADC

But I don't see how that disagrees with my previous point.

Re:Important note:

[martin-boundary]

In your previous points on this thread, you've repeatedly used "bits" incorrectly. A bit is the smallest unit of information. It represents an atomic yes/no question, a single truth value in logic, etc. When you have 2^10 different values, those 1024 values aren't bits. 1024 is only the size of the range of a 10-bit number.

In your ADC example, the bits are the actual 0/1s in the approximation, but the bits are not the waveform approximation itself. That's an actual signal intended to recreate the input signal. The logic flow that's used to make the approximate waveform, that's pure information. And information is measured in units of bits (it can also be measured in other units, eg trits 0/1/2, or nats, etc).

The logic flow is therefore a collection of bits - namely the sequence of zeros and ones that occur in a realization of the algorithm (eg like a length can be viewed as a collection of inches, or a collection of any other valid length units).

Re:Important note:

[Artifakt]

Quantization itself most certainly does stop arithmetic encoding from achieving infinite precision, The fact that the real universe seems to have a minimum length and a minimum interval is why, for just one example, storing all the information that has fallen into a black hole requires the surface area of its event horizon. For the simpler case of a matchstick, you simply cannot infinitely divide the matchstick.
1.616199(97)×10(E-35) meters is as small as things get. That's about 10(E-20) x the diameter of a proton, so not only is no known technology anywhere close to that accuracy, but even if a way was somehow found to reduce the temperature of a matchstick to incredibly near absolute zero, 'notch' a single proton, and read the information back without disturbing the length, we'd still be nowhere close.
Now, how does the universe apply physical laws, when the actual events themselves can be considered as analog computations, either of themselves or other events? Even the simplest equation, such as F=ma, will sometimes produce numbers that are infinite non-repeating decimals (or whatever base the universe uses). The universe doesn't have infinite registers to store those numbers, ergo the real events are only approximate calculations, and the universe, if viewed as a gigantic computer as some people have suggested, fudges its maths.

Re:Important note:

[nedlohs]

Arithmetic encoding isn't marking the length of something and hence running into the planck length rather quickly. It's just a type of compression algorithm, used in practice . I can encode video with dirac just fine thanks, withtout quantum mechanics making it not work - since arithmetic encoding isn't about measuring or marking anything.

I'm sure that the HDDs manufactures were able to produce large enough disks 5 years ago, but they're slowly increasing the capacity, just to force us to buy a new disk every year.

One of the big issues is that when drives hit 2TB a lot of things broke. A traditional BIOS has a hard time booting from a >2TB drive and older operating systems couldn't handle the 4kB sectors either... even if they could build 4TB drives there wasn't much point when you couldn't boot from them and performance was sluggish due to bad partition alignment.

Re:conspiracy

[derGoldstein]

This used to be true with Intel in the 90's, pre-AMD. If there's no competition, there's no motivation to accelerate progress. This is a different case, however -- there is competition in the HDD business, so the motivation to out-do your competitors exists.

This doesn't mean that progress isn't being throttled, however. It's always possible that rivals within the same market are colluding, which is something that's harder to catch.

Re:conspiracy

Very doubtful that all the HDD manufactures had this technology 5 years ago. If all did then one of them would have used it to try to gain an advantage over the others.

Now if only one did, and they were the leader in the field, then yes plausible.

Incorrect: as long as you can measure that mark as a distance with arbitrary precision you can use that to convey any amount of data. For instance, your distance could be 0.7269767679 mm, which, with a simple 1:1 dec to ascii conversion is 0.HELLO, assuming you use fractions of a millimeter for your data. See? With infinite precision comes infinite data. Infinite precision is, of course, difficult to impossible in the real world, but that's never stopped me before.

While platters are often pretty pricy glass, it's still not up there with high purity silicon wafers. In addition, you only have to deposit an even layer of magnetic material - with flash you need not just the semiconductor gates, but the paths to them.

As such, I think that hybrid drives, such as released by Seagate, will eventually dominate. For desktops, hard drives are plenty fast enough for 90% of tasks, but it'd be nice to have the other 10% addressed faster.

1400 calorie diet, not much sodium, healthy, skinny, and pretty good in memory areas, minus that one area damaged from being DEAD for more than half an hour from a car accident.

Gonna be a slow go

[bogie]

Well at least the big price drop part. Ignoring the specifics its like wishing for Ferrari's to drop down to Accord prices. Both products perform the same basic purpose but one uses much different engineering to accomplish the same task. You can make the Ferrari engine cheaper by mass producing it, but it's just always going to be really expensive to produce no matter what. Same thing with SSDs.

Oh how I long for cheap 1TB SSD drives and Gigabyte ethernet Internet wide...

That's just what they told you. You're actually a zombie now.

Yep, you could tell from the laptop HDDs that bigger 3.5" HDDs were possible, because they kept getting denser while desktop HDDs were stuck at 2TB. Nobody really wanted to be the first one out to solve all the issues and educate the market.

Stop ruining people's rants with simple facts and research, it's not very nice.

Re:electron beam lithography

[Calos]

Came here to say exactly this. e-beam is a dead end, it's simply not manufacturable. They have to write every single stinkin' bit on in the whole harddrive individually and serially.

The more interesting part, I think, is discussing why they're exploring this: they're trying to reduce bit size by utilizing a single magnetic particle per bit, instead of several. Sounds like standard litho with pitch doubling or tripling or quadrupling might be able to get the dimensions required. But that's a long, expensive process to develop, compared to e-beam, which is just litho.

Sounds more like they tackled an easy problem on their way to getting to what they really want to investigate, really.

Yay density...

Don't forget, hard disk density is inversely proportional to reliability and life expectancy. I still use 40-80 gig drives that are over 10 years old for all my os drives and you know what? I never suffer data loss. This is because on a low density drive you have a significant amount of redundancy in the wear and tear of moving parts before the errors become unrecoverable. The drives basically get slower and slower as errors increase read time, but they don't fail. This leaves plenty of time to replace the drive and back up all the data when it gets too worn. Not to mention 10 year old hard disks are free. I also know many people who bought 1TB+ drives within the last year or two that have failed already, suddenly and without warning, losing all their data. I sometimes wonder what it would be like if all the modern techniques that have been discovered were put to use making reliable 200gb drives that can run constantly for decades. surely there would be a market for that among people with precious data, sure raid is a better solution but sometimes you want a double layer of reliability. One thing is for sure, will not be buying any 3.3Tb/i disks any time soon.

Less than useful - it uses EBL!

Honestly why does no one seem to notice the part about this where the salt is being used in a "photo" resist for Electron Beam Lithography. That's beam - as in every single surface feature needs to be drawn by a beam of electrons one at a time. The amount of time and expense that would go into the construction of even one 3.5" platter is staggering. Yes it's cool and all but only a military application or James Bond could justify it; ever. An improvement to a mass-produced technology that makes it impossible (and I do mean impossible unless someone comes up with a magical quantum mechanical wave interference pattern that forms the magnetic regions all at once or something) to mass produce is no improvement at all.
