[U. of Tex] Hdd Memory Could Increase Fivefold From UT Research

post #1 of 57
Thread Starter 
Quote:
“In the last few decades there’s been a steady, exponential increase in the amount of information that can be stored on memory devices, but things have now reached a point where we’re running up against physical limits,” said C. Grant Willson, professor of chemistry and biochemistry in the College of Natural Sciences and the Rashid Engineering Regents Chair in the Cockrell School of Engineering.

With current production methods, zeroes and ones are written as magnetic dots on a continuous metal surface. The closer together the dots are, the more information can be stored in the same area. But that tactic has been pretty much maxed out. The dots have now gotten so close together that any further increase in proximity would cause them to be affected by the magnetic fields of their neighboring dots and become unstable
Quote:
There’s a quirk in the physics, however. If the dots are isolated from one another, with no magnetic material between them, they can be pushed closer together without destabilization.

This is where block copolymers come in. At room temperature, coated on a disk surface, they don’t look like much. But if they’re designed in the right way, and given the right prod, they’ll self-assemble into highly regular patterns of dots or lines. If the surface onto which they’re coated already has some guideposts etched into it, the dots or lines will form into precisely the patterns needed for a hard disk drive.

This process, which is called directed self-assembly (DSA), was pioneered by engineers at the University of Wisconsin and the Massachusetts Institute of Technology.
Quote:
“The patterns of super small dots can now self-assemble in vertical or perpendicular patterns at smaller dimensions than ever before,” said Thomas Albrecht, manager of patterned media technology at HGST. “That makes them easier to etch into the surface of a master plate for nanoimprinting, which is exactly what we need to make patterned media for higher capacity disk drives.”

Looks like they are working with Hitachi to see if they can bring it to market. Hopefully this will be implemented.

So we're looking at hard drive capacities in the 10TB range or so. I honestly am not sure I'd be willing to entrust a single piece of hardware with that volume of info. Of course current methods of data redundancy would still apply I imagine...either way this is very cool tech.

I can't even fill up 1TB.

This will be useful for servers, though. One HDD fitting five HDD's worth of data sounds awesome.

If games hit 50GB on average in the next few years, we're going to need it. Photographers looking to get a D800 will breathe a little easier too.

Just because you can't fill up a TB of data doesn't mean it's useless for end consumers... tongue.gif

This for me though would be very ideal.

Old news? http://www.wired.com/wiredenterprise/2012/01/ibm-scientists/ tongue.gif

Pardon me If I'm not that impressed with 10-15TB. We've been at 2TB for how long now? We cram 1TB into laptop drives, why are full size ones only at 2-3, maybe 4TB? What ever happened to yearly upgrades on things, HDDs just kinda... Died.

If you read the article it explains exactly why.

^ It might have to do with the shift to solid state drives

*shrugs* add more platters. Laptop drives can fit 1TB. 3.5" drive platters are much bigger, and you can fit more of them.

Basicly they needed a new way to pack the bits closer together. Did it really take them several years to find this new way?

I'm not normally a conspiracy person, but between the flood, lack of innovation, and continued high-pricing, looks like "people" are pushing for SSDs, which become faster, larger, more reliable and cheaper by the day.

Really? All I've read is that they lose reliability the smaller they get, and that MLC dergades performance in every way (other than cost). It seems to me that every decrease in price is pretty directly tied to a decrease in reliability, but since consumers barely put any stress on the drive we still have a lot of headroom before they make an SSD so bad that consumers will notice.
