Toshiba today confirmed its continued innovation and leadership in the fast
growing market for 1.8-inch hard-disk drives (HDD) with the announcement of two
new drives. The 60GB "MK6006GAH" achieves the highest capacity yet achieved in
this increasingly important HDD format, while the 30GB "MK3006GAL" slims down
drive thickness to only 5mm. Both new 1.8-inch drives draw on Toshiba’s latest
advances in HDD technologies. Most important of these is achievement of the
highest areal density of any 1.8-inch HDD yet commercialized, 93.5-gigabits of
data per square inch. Mass production of the new drives will started in the
third quarter of fiscal year 2004 (October–December).

Toshiba Corporation today confirmed its continued innovation and leadership
in the fast growing market for 1.8-inch hard-disk drives (HDD) with the
announcement of two new drives. The 60GB "MK6006GAH" achieves the highest
capacity yet achieved in this increasingly important HDD format, while the 30GB
"MK3006GAL" slims down drive thickness to only 5mm.

Both new 1.8-inch drives draw on Toshiba’s latest advances in HDD technologies.
Most important of these is achievement of the highest areal density of any
1.8-inch HDD yet commercialized, 93.5-gigabits of data per square inch. This has
allowed Toshiba to pack 30GB of data onto a single 1.8-inch platter, an increase
of 50% over current models, and to deliver drives that are ideally suited for
integration into mobile audio players and mobile notebook PCs. The new drives
are expected to find wide application in products where large storage capacities
must be balanced against the need for a small form factor.

"We are delighted to announce the world’s highest capacity 1.8-inch HDD," said
Seiji Kawagoe, Senior Manager of the HDD Product Planning Department, Storage
Device Division, in Toshiba’s Digital Media Network Company. "We made
improvements to push the capacity, increase shock resistance and to lower power
consumption and noise. The resulting drives are perfect for integration in audio
applications, such as mobile audio players, and mini-notebook PCs. We will
continue to introduce high-capacity, small form factor HDD and contribute to
making a reality of ubiquitous computing."

The key to setting a new areal-density benchmark of 30GB on a single platter—and
realizing a 1.8-inch drive with the largest capacity ever—was replacement of the
Pico Sliders attached to the drive’s heads, which maintain the appropriate
distance from the disk during read and write operations, with Femto Sliders that
are 35% smaller and much lighter. Advances were also achieved in the thin-film
technology for both the head and the platter.

The new drives offer shock resistance of 500G, another new benchmark for
1.8-inch HDDs, the result of use of the smaller, lighter Femto Sliders in
combination with a lighter head-suspension and head arm. Vibration resistance is
also double that of Toshiba’s current models*1, thanks to employment of
feed-forward control in head positioning. In addition, adoption of fluid dynamic
bearing (FDB) motor realizes shock resistance as high as 1,500G during
non-operation, a level ideal for integration in mobile digital devices.

Power consumption of the "MK6006GAH" and "MK3006GAL" are approximately 20% lower
on average than the company’s current drive*1 due to application of pulse width
modulation (PWM) to control of disk rotation speed. PWM switches the power
supply to the spindle motor on and off at a certain frequency. An DC-DC
converter is also used in the power unit.

Low noise operation, as low as 16dB in an idle state, is achieved by FDB motor
and an optimized sinusoidal waveform to control the operational current of the
spindle motor.*2

Mass production of the new drives will started in the third quarter of fiscal
year 2004 (October–December) .

*1 Comparison based on Toshiba’s current 1.8-inch 20GB and 40GB HDD, "MK4004GAH"
and "MK2004GAL"
*2 16dB is for the "MK3006GAL". Noise level for the "MK6006GAH" is 18dB.
