Highest Capacity Slimline 2.5-inch Hard Disk Drive on Market 

A compact form factor combined with high reliability makes the MK-1301MAV
hard disk drives perfect for notebook, sub-notebook and portable
computers. 

IRVINE, Calif., October 16, 1995 -- The world's highest capacity 2.5-inch
slimline hard disk drive was introduced today by Toshiba America
Information Systems, Inc., Disk Products Division (TAIS DPD). The drive,
the MK1301MAV, offers a capacity of 1.35GB and a fast 13ms average seek
time in a small 0.5-inch high (12.7mm), 2.5-inch form factor. 

"While computer notebooks become smaller and thinner, user's demands for
high performance, high capacity storage increases, creating a need for a
very slim hard disk drive that offers higher capacity while delivering
maximum performance," said Anne Stubenrauch, senior product manager, hard
disk drives, TAIS DPD. "The MK-1301MAV drive, which was designed with high
density heads, meets these demands by offering the highest capacity and
the highest performance of any slimline 2.5-inch drive." 

Toshiba designed the MK-1301MAV drive with PRML (Partial Response Maximum
Likelihood) predictive read-channel technology and proven high density
head and media technology to ensure high capacity without sacrificing
reliability. Through these technologies, computer users can achieve
maximum storage capacities plus fast access.

The MK-1301MAV features design and engineering attributes that result in
high performance for portable computing environments. The MK-1301MAV drive
offers a fast 4200rpm rotational speed and a 128KB write cache buffer
which contributes to a peak internal data rate of up to 55.6Mbits/sec.

The MK-1301MAV drive provides users with the highest performance
specifications available in the industry and is available with a Fast ATA
interface to meet OEM, VAR/VAD and system integrator needs. The MK-1301MAV
drive provides fast data transfer rates of 16.6MB/sec in PIO mode 4 and
DMA mode 2.

The new MK-1301MAV drive provides leading performance while still meeting
the demanding size, weight and power requirements of notebook and portable
computers. The new 2.5-inch drive weighs only 5.3 ounces and consumes an
average of only 0.9 watts (idle) from a single 5-volt supply. 

The MK-1301MAV drive's small form factor helps ensure computer notebook
integration. The drive measures a slim 0.5-inches high, 2.76-inches wide
and 3.94-inches deep. The MK-1301MAV drive is also extremely reliable,
demonstrating a 300,000 hour MTBF.

The MK-1301MAV drives are available now in sample quantities starting at
$600.

The MK-1301MAV drive rounds out Toshiba's product offering of 2.5-inch disk
drives to give the company the widest breadth of product line. Toshiba's
complete line of 2.5-inch drives range from 540MB up to 2.16GB, including
