coupled (AFC) media, informally known as
“pixie dust.” This technology sandwiches
a three-atom-thick layer of ruthenium, a
precious metal, between two magnetic lay-
ers on a disk, allowing for a higher areal
density, breaking through limitations of the
super paramagnetic effect.

As a result, the new Hitachi Travelstar
drives are suitable for demanding, high-
capacity Internet, digital audio, video
streaming, and real-time multimedia
applications—whether users
are in the office or on the road. In non-
traditional applications, Travelstar drives
can now incorporate into such products
as Point-of-Sale Systems, Set-
Top Boxes, Telemetry (automobile)
applications, and communications and
entertainment systems.

Enhanced Availability models
Hitachi also offers enhanced availability
features on selected new Travelstar mod-
els. These industry-first models increase
the hard disk drive’s available “power-on”
hours for emerging applications with con-
tinuous operation. At a read/write or data
access rate of up to 50 percent—a typical
usage cycle for 24x7 blade server environ-
ments—the drives are designed to allow
users to leave these drives powered on
around-the-clock.
