IN DISK AND TAPE DRIVES
ON-SITE COURSE FOR SERVO, MECHANICAL AND ELECTRICAL ENGINEERS AND TECHNICAL
MANAGERS IN THE STORAGE INDUSTRY
To understand the many optical and magnetic servo actuation and position
sensing encoding/demodulation schemes
used in magnetic recording machines and the
This practical and comprehensive one day survey course will
familiarize you with a wide range of state-of-the-art sensing and actuation techniques
used in the servo control of high performance storage and computer peripheral products.
Students profit from a very interactive and interdisciplinary classroom environment. By
scheduling this course on-site, attendees are able to freely discuss
design issues of interest to them and to receive expert advie.
Dr. Sidman is a recognized leader in both servo system product development and applied
research. As a pioneer in high performance digital servo systems with 35 years of
experience, he brings a practical perspective and unique interdisciplinary approach that
unite a design team's diverse skills. Participants also benefit from Dr. Sidman's
extensive experience in the simulation and optimization of dynamic systems.

Dr. Sidman is a recognized leader in both servo system product development and
applied research with over 40 years experience spanning a wide
range of industries. As a pioneer and expert in high performance digital
servo systems and adaptive control, he brings a practical perspective and unique
interdisciplinary approach that integrates the diverse skills of your design
team. Participants also benefit from Dr. Sidman's extensive experience in the

Dr. Sidman is the named inventor on 18 U.S.
patents, author of many technical papers and received a Ph.D. from Stanford
University in 1986. As Digital Equipment Corporation's top servo systems guru,
Dr. Sidman was responsible for developing novel servomechanical technology for
disk drives and founded DEC's Servo-Mechanical Advanced Development Group.
The Adaptive Runout Correction System (ARCS) developed by Dr. Sidman in
1977-78 is considered to be the first use of digital signal processing in a disk
drive. Dr. Sidman also pioneered and demonstrated active shock and
vibration correction using angular accelerometer feedback and the use of high
bandwidth actively damped head positioning microactuators in HDDs. Dr.
Sidman is a Senior Member of the IEEE and Past Section Chair of the ASME and has
been a Third Party Provider for The MathWorks since 1994. He founded his
engineering consulting business in 1989.
