The dance continues, HMT's turn to announce their "record":
HMT Technology Corporation Announces Advanced Media Capable of Supporting New World Record Areal Density of 21 Gbit/in2
FREMONT, CALIF.--(BUSINESS WIRE)--May 17, 1999--HMT Technology Corporation (Nasdaq:HMTT - news)
announced today the demonstration of a 20.9 Gbit/in(2) recording density using its advanced ultra low noise, ultra
smooth disk media in conjunction with high density Giant Magneto-Resistive (GMR) recording heads produced by
ReadRite Corp. (Nasdaq: RDRT - news). This areal density translates to greater than 29 Gigabytes of storage capacity on
a single 3 1/2'' diameter disk. The areal density point represents a new world record in storage density.
The HMT media used in this demonstration had a Mrt of 0.4 memu and coercivity of 2500, both values well within
mass production capabilities of HMT's current sputter equipment base. The key to producing this high density media
was using a new five element magnetic alloy in a dual layer configuration for the data storage layer combined with a sub
50 angstrom protective overcoat produced by HMT's newly developed carbon deposition process. As with previous
demonstrations, the media were produced on existing manufacturing equipment. In this work, linear densities of over
480,000 bits-per-inch and track densities of 43,500 tracks-per-inch were achieved with an on track error rate of one part
per billion. A data rate of 175 Mb/sec was used.
Dr. Michael A. Russak, Vice President of Research and Development and CTO at HMT commented, ''This is
extremely good news. We have been working with ReadRite for over two years and have produced several record
breaking demonstrations. We continue to leverage our R&D dollars with this collaboration and as non-captive suppliers
help both companies develop leading edge components which will become available to meet the future requirements of
our customer base.''
