To All,
the direction of technology == 7.2 GB/ platter, or 14.4 GB based on 2 platter jaz format...if they can find the engineers to build it...

Company Press Release
HMT Technology Corporation and Headway Technologies, Inc. Demonstrate
Proximity Recording with MR Heads
FREMONT, Calif.--(BUSINESS WIRE)--April 6, 1998--HMT Technology Corporation of Fremont, Calif., (NASDAQ/NMS:HMTT -
news) and Headway Technologies, Inc. of Milpitas, Calif., announce the demonstration of Proximity Recording at 5 Gb/in(2) areal
density, using high areal density Headway Dual Stripe Magneto-resistive Heads (DSMR) and HMTT ultra-low noise, ultra-low glide
disks. This current areal density capability would support in excess of 7.2 GB on a 3 1/2'' platter. This study demonstrates the exciting
potential for proximity MR magnetic recording for ultra-high linear density.
The DSMR heads used at Headway Technologies for this demonstration consist of narrow track-widths, thin read gaps and a low
fly-height air-bearing design made entirely with today's production processes. The ultra-low noise disks used have Mrt around 0.5
memu/cm(2) and coercivity about 3000 Oe, and were produced on HMT standard manufacturing equipment. The error rate testing was
done at a data rate of 120 million bits per second using a conventional PR4 data channel. Linear density up to 360,000 bit-per-inch and
track density of 13,000 track-per-inch was achieved with on-track error rate better than one part per billion.
This is the highest linear density reported with either GMR or AMR heads. It well exceeds the prior record of 315,000 bpi currently set
using GMR heads. The large signal amplitude, low fly-height and low thermal asperity sensitivity of the DSMR head and the low noise,
low glide height of HMT media are key attributes for the success of this demonstration.
The statements in this news release may contain forward-looking statements that involve risks and uncertainties that could cause actual
results to differ from predicted results. Further information on factors that could affect the company's results is detailed in the company's
reports on Form 10-K for the year ended March 31, 1997 and Form 10-Q for the period ended Dec 31, 1997, as filed with the Securities
and Exchange Commission. The company undertakes no obligation to publicly release the result of any revisions to these
forward-looking statements.
HMT Technology Corporation independently designs, develops, manufactures and markets high-performance thin-film disks. The
company's products are used in high-capacity hard disk drives for a variety of high-end applications, including personal computers,
network servers and workstations, and certain removable hard-disk drive applications. The disks currently being shipped by HMT
primarily have coercivity levels of 2100 to 2700 Oersted, a measure of storage capacity, and glide heights of 1.5 to 0.8 microinches. The
company's shares are traded on the Nasdaq National Market under the symbol HMTT. Additional information may be obtained by
visiting HMT's website at hmtt.com, or by contacting the company directly.
Headway Technologies, Inc. is an independent supplier of conventional as well as proprietary magneto-resistive (MR) recording heads, a
technology used in today's highest-performance disk drives. Led by several of the technology's original innovators, Headway serves the
rapidly growing information storage industry. Founded in 1994, Headway is a privately held company whose principal capitalization
consists of funds managed by two venture capital firms, H&Q Asia Pacific Ltd., an Asian venture group initiated by Hambrecht & Quist
in 1990, and U.S. Venture Partners.
