Toshiba Expands 1.8-Inch HDD Family with World's Highest Capacity for Portable Media Players, Camcorders and Ultra-Mobile PCs
New 120GB-Per-Platter Series Delivers Industry's Highest Areal
Density in 1.8-inch Category for Consumer Electronics and PC Devices
TOKYO--(Business Wire)--
Toshiba Corporation, the pioneer in small form factor hard disk
drives (HDDs), today announced the world's first dual-platter 240GB(a)
HDD (MK2431GAH). The new drive delivers the highest capacity(a) and
areal density in the 1.8-inch drive category for integration into
portable media players, camcorders and mobile PCs. Toshiba also
announced new 120GB (MK1231GAL) and 80GB (MK8031GAL) capacity
offerings, rounding out the most complete line of high-capacity 4,200
RPM 1.8-inch HDDs for consumer electronics (CE) and mobile PC system
manufacturers.
The new 240GB drive and 80GB drive will enter mass production at
the end of September, and the 120GB is now in mass production.
Toshiba's 240GB MK2431GAH and 120GB MK1231GAL achieve an areal
density of 344 gigabits per square inch (531.9Mbit/mm2), the
industry's highest areal density(a) in the 1.8-inch form factor, using
perpendicular magnetic recording (PMR) technology, which Toshiba
introduced and commercialized in 2005. Toshiba's technology leadership
in PMR has enabled the company to consistently deliver leading-edge
capacities in the 1.8-inch form factor to support growing demand for
miniaturization without sacrificing capacity for digital video, photo,
audio and computing applications.
The new 1.8-inch HDD series uses a new mechanical and firmware
design for enhanced durability, making the 80GB and 120GB
single-platter HDDs well suited for slim-line mobile gadgets and PC
applications. The new dual-platter 240GB MK2431GAH product is
especially suitable for high-end digital video camcorders as well as
light-weight mobile PC applications which require high capacity and
high shock resistance to protect the users' valuable digital assets.
The new design elements incorporated in the MK2431GAH optimize
power efficiency to new levels with a 33 percent overall reduction in
energy consumption efficiency(b) over Toshiba's previous-generation
model of MK1626GCB (160GB 3,600 RPM) 1.8-inch HDDs.
Toshiba Group, a Corporate Citizen of the Planet Earth, is
committed to realizing a better environment. Guided by "Toshiba Group
Environmental Vision 2050" the Group is implementing measures to boost
environmental efficiency by 10 times in FY2050, against the benchmark
of FY2000. The core target is to reduce projected CO2 emissions by a
total equivalent to 117.7 million tons a year by FY2025, through the
development and sales of highly efficient power supply equipment and
systems, and the manufacture of environmentally conscious home
appliances and office equipment. By working to mitigate global
warming, make efficient use of resources and control management of
chemicals, Toshiba Group creates value for people and promotes
lifestyles in harmony with the Earth.
Key Features of New Products
1. Achieving areal density of 531.9Mbit/mm2 (344Gbspi).
MK2431GAH and MK1231GAL achieve an areal density of 531.9Mbit/mm2,
the result of improving the read-write head and of an enhanced
magnetic layer. With the same two platter 1.8-inch design as Toshiba's
current 160GB product, MK2431GAH offers a 240GB capacity, the highest
yet achieved.
2. Improved energy consumption efficiency(b).
Compared to the current 160GB MK1626GCB, the new MK2431GAH
improves energy consumption efficiency(b), as defined under the
Japanese legal standard, to 0.0013W/GB, a 33% improvement.
3. Environmentally conscious products
(1) Lower CO2 emissions during the product lifecycle(c)
During their lifecycle, the MK1231GAL will lower CO2 emissions by
approximately 54g a year.
(2) RoHS compatible
The new drives comply with the European Union's RoHS directive(d)
for eliminating use of six hazardous substances in electrical and
electronic equipment.
(3) All new products meets standards for certification as a
standout Toshiba ECP
Toshiba promotes an "Excellent ECP" program to stimulate creation
of high value products offering exceptional environmental
friendliness. For more information, visit

(a) The industry's largest commercially available capacity in
1.8-inch hard disk drive, as of Sept 10, 2008 (source: Toshiba)
(b) Energy consumption efficiency is calculated based on power
consumption divided by formatted capacity, as defined by Japanese law.
(c) Comparison based on MK6015MAP (Year 2000 model). Based on
Toshiba's evaluation method of LCA (Life Cycle Assesment).
(d) The RoHS Directive, which came into effect in July 2006, is a
European Union directive that eliminates the use of six hazardous
substances in electrical and electronic equipment.
