An industry

fi

rst, the Hitachi Deskstar 7K1000 hard disk drive delivers up to one terabyte of

storage capacity for demanding consumer and commercial computing products. It leverages
the industry’s most reliable perpendicular magnetic recording (PMR) techniques and the latest
advancements in silent acoustics, shock protection, and head technology to maximize capac-
ity, performance and

fi

eld reliability. Best-in-class power management and thermal emissions

help manufacturers meet energy compliance targets and extend drive life.

Proven PMR technology

Field-proven in 2.5-in. drives, Hitachi’s PMR implementation continues to demonstrate
reliability equal to or exceeding conventional longitudinal technology. The Deskstar 7K1000’s
second-generation PMR head and media technology improves noise characteristics and
thermal stability.

Reduced power idle modes

Unique to Hitachi drives, the Deskstar 7K1000 features three advanced low-power idle
modes—active, unload and low-power. Together, they reduce power consumption at the drive
level up to 20%, optimize non-operational latency and lower drive temperature for cooler
system operation.

Outstanding shock resistance and power effi ciency

Through a patented ramp load/unload design disk heads (in non-operating modes) are
unloaded to a ramp outside the disk where they rest in a low-power ‘unload idle’ state until
activated. In low RPM drives, this can reduce power by up to 50%. Ramp load/ unload
provides tangible bene

fi

ts for the drive and host product. It greatly minimizes the risk of shock

damage by eliminating direct contact between the heads and disks. Reduced wear and heat
improve overall drive reliability. In the event of power loss to the drive, heads are unloaded
using energy extracted from the spinning disks. This patented power-saving feature helps to
reduce overall maintenance costs and extends the drive service life.

Another contributor to Deskstar 7K1000’s exceptional shock performance and power savings
is the use of compact, low-mass femto air-bearing sliders.

Extended fi eld reliability

An integrated thermal sensor monitors operating temperature, enabling the host processor to
intelligently adjust air

fl

ow as needed for cooling. Sensor integration reduces component cost

and increases reliability.

Deskstar 7K1000’s thermal

fl

y-height control (TFC) uses an integrated heating element to

precisely maintain a constant

fl

y-height throughout read and write operations. This reduces

raw soft error rate and, in turn, improves overall data integrity, drive performance and reliability.

Deskstar 7K1000’s iridium-manganese-chromium (IrMnCr) read head sensor technology offers
better performance and reliability in harsh conditions.
