Researchers Discover Way to Extend HDD Storage 5X

Heat assisted magnetic recording has been a long time favorite, but scientists have found another approach to reduce the space between magnetic dots on HDD platters and preventing them from impacting each other at the same time.

At least in the lab, the technology uses a direct self assembly approach and would provide a five-fold increase of HDD storage density, breathing four to five more years of life into HDDs.

The idea is based to build tiny "walls" between the dots. The researchers used block copolymers, which lack magnetic properties and can assemble themselves automatically in a "highly regular patterns of dots or lines". If there is already a surface with "guideposts" in place, they can be forced to establish a desired pattern of walls to allow dots to be aligned in a much denser pattern than it is the case today, the scientists claim.

The viability of the discovery depends, of course, on its ability to be introduced into mass-production.  The researchers said they are working with HGST to evaluate how easily and economically direct self assembly could be used in HDD manufacturing. In the lab, they said that the block polymers can align themselves in about 30 seconds in "some cases".

    Short-sighted people: "No need for more HDD capacity other than pornography."

    Back in 2000's: "No need for more than 32 GB of HDD capacity..."

    See. I still can't justify an SSD. My PC boots up in 40 seconds, and my games load in 5 seconds. Why do I need more than that now?

    I will get an SSD when 1 TB is $100. But by then I would probably require at least 2 TB...

  • Vapor until applied. This is nice to know but completely meaningless until it gets to market. Thanks for the nothing news.

    I remember a guy telling me back in the late 90's that people wouldn't need more than 5gb of space..

    See. I still can't justify getting a quadcore. My PC still gets decent frame-rates on a P4 clocked at 2.0 GHz.

    Depends on what you do. If you work all day on a PC these saved seconds add up.
    Kinda like going from a 4cyl to a 6 cylinder engine. Once you drove one you do not want to go back; even if you drive only the speed limit.

    Face it, you need an SSD. Anything less than instant is not good enough. Or at least that will be the case within a few years.

    Try installing 50 Windows updates, copying 100GB of data of small files to your drive, installing a new version of Matlab, running a virus scan or running bittorrent on a 100Mb/s internet connection while playing games.

    Let me know how long it takes you/how smoothly it runs. Or run out of memory and watch you pitiful 1TB hard drive grind away while your computer is unusable. SSDs crunch through low memory situations pretty well. They kick butt and they can handle 100s of Terabytes of writes.

    And my 4 year old Core 2 Duo (3GHZ) laptop with a 3 year old SSD boots up in 18 seconds, 8 seconds if you start after POST. http://youtu.be/lyTJ-4dEqsY

    I have a second internal laptop drive for storage.

    See. I still can't justify getting a 6 cylinder engine. My 4 cylinder is still quicker and more fuel efficient than most bigger engines. Turbos are like hyperthreading for cars.

    See. I still can't justify using air service to transport extremely perishable products. Shipping them over water is acceptable, even if my factory's production grinds to a halt while waiting for such products.
