Improved "pixie dust" for double the magic in hard disk drives
IBM introduced the world's highest capacity mobile hard disk drive at 80
GB -- made possible by enhancements to the company's patented "pixie dust"
technology, boosting storage density by 100 percent.
IBM also announced plans for a new 7200 RPM performance category, offering
workstation performance with freedom of mobility.
The new Travelstar 80GN breaks current areal density records by allowing
up to 70 billion bits of data to be written on each square inch of disk
space. IBM achieved this by adding another coating of "pixie dust" -- or
an additional ruthenium/magnetic layer to create a five-layer sandwich
called laminated-"pixie dust."
The additional layers bring about an even higher signal-to-noise ratio
which allows data recording at ultra high densities while maintaining data
integrity. With this new data density record, IBM is quickly approaching
the 100 gigabits/square inch the company predicted "Pixie Dust" would
achieve in 2003.
Announced last year, "pixie dust" is an IBM data storage breakthrough
achieved by sandwiching a three-atom-thick layer of the element ruthenium,
a precious metal similar to platinum, between two magnetic layers --
technically called antiferromagnetically-coupled media. That only a few
atoms could have such a dramatic impact caused some IBM scientists to
refer to the ruthenium layer informally as "pixie dust."
The Travelstar 80GN is based on proven reliability and a mature design
with high shock robustness and low power consumption. A new 8 MB cache
contributes to making the 80GN the world's highest performing 4200 RPM
mobile hard drive. In addition, IBM reduced drive operating acoustics by
as much as four decibels, continuing the Travelstar 80GN's leadership as
the world's quietest mobile hard drive.
