Industry-leading capacity, performance, and acoustics
Hitachi Travelstar 60GH and 40GN
2.5-inch hard disk drive
Highlights
Advances notebook hard drive leadership with the highest capacity, highest performing drives
Offers new models that operate with the Enhanced Availability feature
60GH—the fourth generation of 5,400rpm models—offers highest capacity and highest performance in the
industry with a 60GB capacity
40GN provides areal densities of up to 34Gbits/sq.inch, yielding up to 20GB of capacity per disk
All models contain Fluid Dynamic Bearing (FDB) motor technology for industry-leading idle and operating
acoustic performance
Travelstar provides industry-leading operational shock rating of up to 200Gs (2ms)
Travelstar leverages latest antiferromagnetically coupled (AFC) media, also known as “pixie dust”
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 com-
bines AFC Media, Fluid Dynamic Bearing
(FDB) motor technology, an ATA-100 inter-
face, 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 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.
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 tem-
peratures.
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.
Advanced mobile systems
The Travelstar 40GNX redefined state-
of-the-art storage for mobile computing.

Feature Benefit
First 60GB mobile hard drive and the fourth- Hitachi Travelstar 60GH has the industry-leading capacity
generation 5,400rpm model in the industry and performance to enable mobile users to work with a
new range of emerging storage-intensive applications.
Drive Noise Suppression System (DNSS) Hitachi Travelstar 60GH and 40GN incorporate state-of-
• Fluid Dynamic Bearing (FDB) the-art noise suppression technology for industry motors on all models leading quiet operation.
• VCM acoustic dampening
Fast Ultra-DMA 100 2.5-inch Hitachi Travelstar 60GH and 40GN all feature industrymobile hard drives standard high data transfer rates to help ensure ultimate
performance.
High max areal density of 34Gbits/sq. inch Hitachi Travelstar 40GN maximizes areal density to enable
resulting in up to 20GB of capacity per disk more data storage per disk in standard, compact pack
ages.
Industry-leading operating shock rating Hitachi Travelstar 40GN provides exceptional ruggedness
(200Gs/2ms) for a 2.5-inch mobile hard drive to help withstand shock during read/write operations.
Antiferromagnetically-coupled (AFC) The Hitachi Travelstar family incorporates AFC “pixie dust”
media on all models technology, allowing for higher areal density.
