Seagate Overcomes Superparamagnetic Limit

Posted by chrisd on from the my-1gb-microdrive-just-died dept.

Longinus writes "Yahoo! News is reporting that hard drive manufacturer Seagate has "overcome a significant challenge in magnetic memory with a new technology capable of achieving far beyond today's storage densities -- up to as great as 50 terabits per square inch. Currently, the highest storage densities hover around 50 gigabits per square inch, but Seagate said its heat-assisted magnetic recording (HAMR) technology could break through the so-called superparamagnetic limit -- a memory boundary based on data bits so small they become magnetically unstable." Perhaps the near future of storage technology lies, for now, not in nanotech or holography, but still in magnetic recording."

  1. Solid State Memory? by T-Kir · · Score: 5, Interesting

    Yeah, but what is the current progress on the solid state memory devices? I know that there is a Cambridge university team who have got their own division working on this.

    If I remember rightly (this info I read about 3 years ago) they said that they had some HDD manufacturers (probably IBM at the time) were very interested in the tech, and their initial projections were about 2.2TB for a credit card sized module. Although they were still early in research/development, I wonder how they (or any others) are doing now?

  2. Re:Moore is my wallet's friend by f00Dave · · Score: 5, Interesting

    This is *way* beyond Moore's Law, though. They're proposing a thousand-fold increase in storage densities, which equates to (approximately) ten doublings, not one every year and a half. According to Moore's Law, we shouldn't be approaching those densities for another 15 years....

    So, who's been lying to us all along? The hard drive manufacturers or the physicists? =]
