Fujitsu heeft een nieuwe harddisk media technologie ontwikkelt waarmee 300Gb data op een vierkante inch geparkeerd kan worden. De datadichtheid van deze 'LEXIS' technologie is drie keer zo hoog als wat met huidige technologiŽn mogelijk is:
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.
The details of the new media technology will be announced at the International Magnetics Conference in Toronto, Canada, which will take place from April 9. A portion of this technology is based on research sponsored by ASET (the Association of Super-Advanced Electronics Technologies).
