Hard Disk Drive Servo Systems, 2nd edition (Chen, B.M. et al.; 2006)

Part I of this book briefly discusses the history of hard drive control and the disk drive servo loop before delving in-depth into system identification and then linear and nonlinear control theory. Part II then applies the concepts of Part I to solve track-seeking, track -following , and dual-stage control problems. The book focuses almost exclusively on feedback controllers for track-following and track-seeking control.This book should be considered a must-read for those directly involved in those areas. All of the control approaches presented in the book have convenient Matlab implementations in the authors´ downloadable toolbox.
