Subject: [LIB] 360 Gb hard drive in 4 years
Hi Everyone,
Anyone fancy a 360 gb hard drive in their Libretto!!
Thursday 9th May 2002
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) 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 on 2 May by Fujitsu
Laboratories Ltd., one of the world's premier technology research centres,
at Intermag Europe 2002 in Amsterdam, The Netherlands.
Fujitsu's latest technology advancements feature a new
Current-Perpendicular-to-Plane (CPP) mode Giant Magneto-Resistive (GMR) 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, making possible an 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 movies. According to 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."
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), 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 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.
