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".

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

    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..."

    CaptainTomSee. 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...


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

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