Where is Seagate headed with its perpendicular technology?
Joni Clark: Perpendicular technology will continue to be the recording method used. At some point in approximately 5-8 years, the use of HAMR (Heat Assisted Magnetic Recording) will work to increase areal densities even further on perpendicular drives. HAMR allows increased densities through the use of lasers and heat applied to the media. Ultimately, areal density limits are expected to reach as high as 50 Tb/in2 (Terabits per square inch) using perpendicular along with HAMR and patterned media technologies.
