Reduced power idle modes
Unique to Hitachi drives, the CinemaStar
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 tempera-
ture for cooler system operation.
Outstanding shock resistance and power
efficiency
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 benefits for the drive
and end product. It greatly minimizes the risk
of shock damage by eliminating direct con-
tact 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 CinemaStar 7K100’s
exceptional shock performance and power
savings is the use of compact, low-mass
femto air-bearing sliders.
Extended field reliability
An integrated thermal sensor monitors operat-
ing temperature, enabling the host processor
to intelligently adjust airflow as needed for
cooling. Sensor integration reduces compo-
nent cost and increases reliability.

An industry first, the Hitachi CinemaStar™
7K1000 hard disk drive delivers up to one
terabyte of storage capacity for demanding
consumer electronics (CE) devices. 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 capacity, performance and reliability.
Best-in-class power management and thermal
emissions help manufacturers meet energy
compliance targets and extend drive life.
Optimized for exceptional quality of service
(QoS) in streaming applications, CinemaStar
7K1000 is ideal for recording and playback of
today’s high-definition (HD) formats.
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 CinemaStar
7K1000’s second-generation PMR head and
media technology improve noise characteris-
tics and thermal stability.
Exceptional streaming audio/video
CinemaStar 7K1000’s advanced firmware
improves data integrity and optimizes QoS to
meet the deadlines in streaming applications.
Together, the SMART command transport
protocol and Hitachi Smoothstream™ tech-
nology minimize disruptions in stream delivery
by adapting buffer management behavior and
error recovery timing to match the characteris-
tics of typical streaming applications.
Silent seek acoustics
Optimized for ultra-quiet operation, sound
emissions during idle and seek operations
are virtually undetectable by the human ear.
There’s no disruption to entertainment or to
other activities during background recording.
