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 25 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.
Course Objective:
Understand the many optical and magnetic servo actuation and position sensing encoding/demodulation schemes used in magnetic recording machines and the tradeoffs involved.
Course Outline:
Historical perspective of servo tracking in magnetic and optical disk drives.
Survey of various disk drive and tape drive position transduction schemes.
Issues in the development of tracking error budget, including sensing errors and physical disturbances.
Survey of servo mechanisms and actuation methods: old, new and things to avoid.
Participants each receive about 300 pages of course notes containing detailed information about disk and tape drive servo sensing and actuation techniques used in products.

This course is intended for engineers and technical managers involved in digital servo controlled positioning system product design. Those most benefiting include mechanical, electrical and control system designers of digital servo systems, drive mechanics, real time/DSP hardware and software, and those wishing to keep abreast of rapidly evolving control technology. Your engineers will benefit from Dr. Sidman's extensive experience as have the many hundreds of engineers and managers worldwide who have attended his courses.
Dr. Sidman is an independent engineering consultant with 25 years of practical industrial design experience. He is an expert in digital servo systems and disk drive head positioning servo control, with roles spanning product design, advanced development and applied research. He 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 headed the Storage Division'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 disk drive shock and vibration correction using an HDA mounted angular accelerometer and the use of high bandwidth microactuators in HDDs over ten years ago. Dr. Sidman is a Senior Member of the IEEE and a Member of the ASME and has been a consultant to and Third Party Provider for The MathWorks since 1994. He founded his engineering consulting business in 1989 and is listed in Marquis Who'sWho in Science and Engineering 1998-1999.
