Fujitsu, a world leader in hard disk drive technology, has developed revolutionary new read head and media technologies that will enable hard disk drive (HDD (Hard Disk Drive) See hard disk and HDD caddy.

) recording densities of up to 300 gigabits per square inch (Gb/in2). The new technologies are expected to lead to the commercial introduction within two to four years of 2.5" hard disk drives with capacities up to six times the recording density available today. The breakthroughs, which come less than a year after Fujitsu announced record-breaking 100Gb/in2 technology, were announced by Fujitsu Laboratories Ltd., one of the world's premier technology research centers, at Intermag Europe 2002 in Amsterdam, The Netherlands, on May 2.

Fujitsu's latest technology advancements feature a new Current-Perpendicular-to-Plane (CPP cpp - C preprocessor. ) mode Giant Magneto-Resistive (GMR (Giant Magnetoresistance) See magnetoresistance. ) head that achieves more than three times the playback output levels of current HDDs by allowing current to flow perpendicular to the GMR element. Existing GMR read heads, which operate in the Current-in-Plane mode, are considered to have a limit of approximately 100Gb/in2 in density due to their small signal output level. Fujitsu's new CPP GMR head also boasts improved sensitivity to data signals. Higher sensitivity when element size becomes smaller results in increased recording density.

"Fujitsu is a pioneer in hard disk drive component technology," said Dave Reinsel, industry analyst at IDC. "Through these technological advancements, the company has proven the viability of future disk drive component technology and has routed a path for advancing AD beyond forecasted requirements, as well as enabling future industry migration to small form factor drives."

In addition to breakthrough read head technology, Fujitsu announced a new advanced media technology at the Intermag conference. Building on the 100Gb/in2 media demonstration announced in August 2001, Fujitsu researchers demonstrated for the first time that a linear density of over one million flux changes per inch (1000 kFCI) could be recorded on Synthetic Ferrimagnetic Media with longitudinal recording The common method of digital recording on a magnetic material. The bits are laid out end to end, and the direction of the magnetic charge is horizontal with respect to the medium.

It typically refers to disk drives, where the number of bits per inch (bpi) times the number of tracks per inch (tpi) yields the areal density.  of 150Gb/in2. This indicates that 300Gb/in2 is achievable using the Advanced Synthetic Ferrimagnetic Media together with high sensitivity read heads.

Within the next two years, Fujitsu expects to implement these technologies in the commercial production of 2.5" hard drives. Within four years, Fujitsu further expects to achieve capacity increases of up to 360GB -- enough to record 76 high-quality DVD DVD: see digital versatile disc.

 Fujitsu, those increases will drive growth in the market for 2.5" HDDs in PCs, consumer electronics devices, and other products and will eventually render the 3.5" desktop HDD obsolete.

"Fujitsu is proud to once again offer a technology breakthrough that will lead to better and faster products for tomorrow's consumers," said Mike Chenery, vice president, advanced product engineering at Fujitsu Computer Products of America, Inc. "Fujitsu Labs' outstanding research breakthrough, which extends a string of technology advancements that remain largely unsurpassed and unanswered by other vendors, demonstrates our commitment to staying at the forefront of HDD technology."

Fujitsu's Tradition of HDD Technology Leadership

The latest breakthrough highlights one of many Fujitsu achievements in its long history of technology leadership. In 1998, Fujitsu was the first to integrate across its entire HDD line the Giant Magneto-Resistive read head that is the defacto standard in all hard disk drives today. Later, in 2000, Fujitsu developed and integrated Fluid Dynamic Bearings (FDB FDB Fluid Dynamic Bearing (hard disk technology)

), the first successful implementation of this HDD motor design in desktop hard drives. Also in 2000, Fujitsu developed a pioneering media technology that integrated a layer of Ruthenium ruthenium (rthē`nēəm), metallic chemical element; symbol Ru; at. no. 44; at. wt. 101.07; m.p. about 2,310°C;; b.p. about 3,900°C;; sp. gr. 12.  on the disks. Synthetic Ferrimagnetic Media, as Fujitsu has termed the media, allows tighter packing of data and more accurate reading of information from disks.
