Seagate Cites HDD Record - 1 Terabit per Square Inch

Seagate reported a new milestone for hard disk drive density -- 1 terabit (1 trillion bits) per square inch. The technology demonstration used heat-assisted magnetic recording (HAMR). Current HDDs use Perpendicular Magnetic Recording (PMR), which was introduced in 2006 to replace longitudinal recording, a method in place since the advent of hard drives for computer storage in 1956, and is expected to reach its capacity limit near 1 terabit per square inch in the next few years.


Seagate said HAMMR technology could give rise to 3.5-inch hard drives with a capacity of up to 60 terabytes over the next 10 years.
