                       ``THE MARCH TOWARD 1 TERABIT/In2:
                 ISSUES IN RECORDING HEAD DESIGN AND FABRICATION''

                               Prof. James A. Bain
                  Department of Electrical and Computer Engineering
                             Carnegie Mellon University

                                      Abstract

In current magnetic recording systems, increases in performance are gated
by the available of fast sources of magnetic field to write bits on the media.
Until the last decade, improvements had been gated by sensor signal to noise.
However, with the advent of magnetoresistive readback sensors in disk and
tape systems, the burden has shifted to the write head. In this talk, I will
discuss how write heads form a bottleneck for future advances in data storage
systems. This will be followed by a summary of recent research on higher
efficiency head designs and higher moment pole materials to respond to this
problem. I will also discuss some of the metrology issues associated with
making advancements in this area. As a harbinger of things to come, I will
touch outline on more advanced solutions to this problem that are also
being pursued within the DSSC and elsewhere for the longer term. These
include including thermally assisted recording, patterned media,
exchange-coupled media, perpendicular recording, and probe-based storage.

Dr. James A. Bain has been on the faculty of Carnegie Mellon University,
Department of Electrical and Computer Engineering since 1995, having
started there as a post-doctoral researcher in 1993. He received his BS in
Materials Science and Engineering from the University of Pennsylvania in
1988. He went on to receive his MS and Ph.D., also in Materials Science
and Engineering, in 1991 and 1993, respectively, from Stanford University.
His work is centered in the Data Storage Systems Center, a National
Science Foundation Engineering Research Center, which is the largest
academic research effort in data storage within the US. Since 1999, he has
also held a courtesy appointment in the Department of Materials Science
and Engineering at Carnegie Mellon. His research interests are in the area
of thin film magnetic devices, specifically magnetic recording heads, and in
systems integration for magnetic recording. He currently leads the tape
recording research thrust within the DSSC. Dr. Bain has co-authored over
40 papers in the area of magnetic thin films and magnetic recording, and is
a member of the Materials Research Society and the IEEE Magnetics
Society. More info about Dr. Bain can be found at
