(Phys.org)—TDK has realized increased areal density of its hard disk drives. TDK has set a new record, compared to previous areal density at 1Tbit/inch2, with the new stat of increased density to 1.5Tbits/inch2. The point of all this is that TDK can say it will offer 1TB of storage per platter in a 2.5-inch hard drive, and 2TB of storage per platter in a 3.5-inch drive. TDK used a technique that combines platter technology from Japanese firm Showa Denko (Showa Denko Platters) with their refined read-write heads. Showa Denko's disk platter is based on perpendicular magnetic recording with discrete track recording (DTR) superimposed on it.
