IBM Creates Working "Racetrack Memory"

Posted by kdawson on from the and-they're-off dept.

holy_calamity writes "IBM has created the first working 'racetrack memory' device — a technology we've discussed as it's been touted as the future of memory. It works by writing bits using the magnetic domains inside a very thin wire. Those domain can be shunted along this 'racetrack' and past read heads."

    Doesn't anyone remember the "bubble memory"? from the 70's and 80's and was a loop racetrack type device.

    Ah, no. Mercury delay line storage actually used acoustic waves in a tube of mercury to store pulses, which were regenerated by amplifiers and sent back into the tube by the actuator. This thing with the loop of wire and the magnetic bits moving while the wire stays still sounds much more like the idea of magnetic bubbles in bubble memory.
