IBM have just announced that its researchers have been able to cut a bit size from one million to 12 atoms making the five years of research worthy of future storage hardware like hard disk drives and flash chips that are 100 to 150 times larger that what we have today.
“Looking at this conservatively … instead of 1TB on a device you’d have 100TB to 150TB. Instead of being able to store all your songs on a drive, you’d be able to have all your videos on the device,” said Andreas Heinrich, IBM Research Staff Member and lead investigator on this project.
This breakthrough technology uses unconventional form of magnetism called antiferromagnetism where atoms spins in opposite directions unlike to what we have today on our ferromagnetic storage devices where atoms are aligned in one directions. The antiferromagnetism results enables scientists to create a 100 times denser atomic-scale magnet memory to what we have today on our normal HDDs and SSDs.
