Toshiba achieved the world’s first 100GB 2.5-inch HDD by establishing a new
benchmark for areal density: 80-gigabits of data per square inch. The key to
achieving this was replacing the Pico Sliders attached to the drive’s heads, and
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 drive’s shock resistance of 3,185 m/s2 (325G, 2msec) is 50%
higher than in Toshiba’s current 2.5-inch HDD*, due to employment of the
smaller, lighter Femto Sliders in combination with a lighter head-suspension and
head arm.

Power consumption of the "MK1031GAS" is approximately 20% lower on average
than the company’s current drive* due to pulse width modulation (PWM) that
controls disk rotation speed by switching the power supply to the spindle motor
on and off at a certain frequency. A DC-DC converter is also used in the power
unit. Low noise operation, as low as 21dB in an idle state, is achieved by an
optimized sinusoidal waveform to control the operational current of the spindle
motor. Samples of the MK1031GAS will be available in May.

Toshiba today confirmed its leadership in the fast growing market for
2.5-inch hard-disk drives (HDD) with the announcement of the "MK1031GAS," the
highest capacity drive yet achieved in this increasingly important form factor.
Making full use of Toshiba’s latest advances in HDD technologies, including the
highest areal density yet commercialized, the new HDD delivers a 100GB storage
capacity, and does so in a drive only 9.5mm high. "MK1031GAS" is ideally suited
for integration into portable PCs, especially those with advanced audio-visual
capabilities that need the capacity to handle large video sources.

"We are delighted to announce the world’s highest capacity 2.5-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 drive is perfect for integration in high
spec portable PCs and other portable devices. Our strategy is to create the
technologies and products that make a reality of ubiquitous computing, and we
are sure the "MK1031GAS" makes a valuable contribution to that."
