AFC Media - Extending the Limits of Longitudinal Recording
Overview The 100 gigabit density milestone was once thought unattainable due to the superparamagnetic effect. Hitachi Global Storage Technologies' (GST's) breakthrough discovery of antiferromagnetically-coupled multi-layers broke this barrier and enabled significant areal density increases while maintaining the thermal stability of recorded data. This advancement permitted magnetic hard disk drive technology to extend far beyond the previously predicted "Limits" imposed by the superparamagnetic effect. Mass production of the first hard drives with AFC media began in May, 2001 with Hitachi GST's 2.5-inch Travelstar 15GN and 30GN products which featured 15-gigabytes-per-platter and an areal density of 25.7 gigabits/inch2.
