It's about at this point that at least some people feel that magnetic storage will begin to lose steam because of something called the superparamagnetic limit. Whether that is true and whether alternative storage technologies will arrive in the nick of time, like U.S.
That's what happens when a material reaches the superparamagnetic limit.
IBM, of course, isn't the only company in the hunt for ways to surpass the superparamagnetic limit. TeraStor Corp., San Jose, Calif., is working on a near-field technology that combines magnetic recording with laser optics.
TeraStor's technology evades the superparamagnetic limit in several ways.
Hard drives are approaching the superparamagnetic limit
, a phenomenon that relates to the size of the magnetic particles on the disc platter being so small that they spontaneously rearrange themselves, making it impossible to store data at unlimited densities.
