Forgive if a repost, I only did a quick search.
Hitachi achieves industry-leading areal densities via Perpendicular Recording
In March 2005, Hitachi Global Storage Technologies demonstrated an areal density of 230 gigabits per square inch (Gb/in2) on perpendicular recording technology, the highest areal density achieved to date based on vertical recording. This accomplishment represents a doubling of today’s highest data densities on longitudinal recording technology. At the current rate of growth, Hitachi expects to see products shipping at 230 Gb/in2 in 2007, translating into storage capacities of up to 20 gigabytes* on Hitachi’s one-inch Microdrive and up to one terabyte on the Hitachi 3.5-inch Deskstar hard drive.
A flash movie about how it works. Warning... Very Corny!!! (http://www.hitachigst.com/hdd/research/recording_head/pr/PerpendicularAnimation.html)
