Leading-edge technology
Mobile storage leadership continues with
the Hitachi Travelstar 60GH and 40GN
hard drives. The Travelstar 60GH is the
industry’s first 60GB notebook hard disk
drive employing four disks in a 12.5mm
high design and is the fourth-generation of
5,400rpm mobile drives in the industry.
The innovative hard drive design combines
AFC Media, Fluid Dynamic Bearing
(FDB) motor technology, an ATA-100 interface,
giant magnetoresistive (GMR) head
technology, Partial Response Maximum
Likelihood (PRML) digital channel, a
head load/unload feature, and Enhanced
Adaptive Battery Life Extender™ (ABLE)
3.0. This design provides the exceptional
quietness, storage capacity, performance,
power management, quality, and reliability
required by today’s notebook systems.
The Travelstar family of hard disk drives
incorporates the latest storage technology—Antiferromagnetically-coupled (AFC) media, informally known as
“pixie dust.” This technology sandwiches
a three-atom-thick layer of ruthenium, a
precious metal, between two magnetic layers
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, highcapacity
Internet, digital audio, video
streaming, and real-time multimedia
applications—whether users
are in the office or on the road. In nontraditional
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.
Performance and reliability
The Hitachi Travelstar 60GH and 40GN
hard drives use proven storage technology
such as TrueTrack Servo, Drive Fitness Test™
(DFT), and Self-Monitoring Analysis and
Reporting Technology (S.M.A.R.T.), as well
as a thermistor, an adaptive control device
that helps maintain high performance and
fast seek times at high environmental temperatures.
Enhanced Availability models
Hitachi also offers enhanced availability
features on selected new Travelstar models.
These industry-first models increase
the hard disk drive’s available “power-on”
hours for emerging applications with continuous
operation. At a read/write or data
access rate of up to 50 percent—a typical
usage cycle for 24x7 blade server environments—the drives are designed to allow
users to leave these drives powered on
around-the-clock. |  |
Advanced mobile systems
The Travelstar 40GNX redefined stateof-
the-art storage for mobile computing.
The reduced acoustics, high speeds,
and capacities of Hitachi Travelstar drives support superior digital content creation capabilities,
higher quality digital audio and
video, and significantly faster processing
for data-intensive multimedia and Internet
applications.
By using one of the new Travelstar drives
in a laptop system, you can unchain
your multimedia studio from the desktop,
enabling high-end multimedia creativity as
mobile as your imagination.
Hitachi quality, support, and
service
The Hitachi Travelstar mobile hard disk
drives share common field-proven components
to provide manufacturers with
superior-quality hard drives backed by
HItachi warranty and technical support
and services.
