"..Fujitsu has succeeded in developing a new type of recording media, called LEXIS (Layer Exchange Interaction Stabilized), which has the potential to achieve three times the density of the current theoretical limit governed by thermal fluctuation of magnetization.
The new media technology will be used to expand the capacity of hard-disk drives (HDDs) for information storage devices for computers and home information electronics products. Using the new media technology together with a newly developed head, Fujitsu has already demonstrated a recording density of 56Gb/sq. inch -- the world's best performance as of today.
With this density, a 3.5-inch HDD containing two disks could store about 30 movies in DVD-quality video. Moreover, when used together with high-output heads, the new media technology has the potential to achieve a recording density of 300Gb/sq.in.."
