Hard Disk Drive

Explore the challenges presented by modern hard disk drives and learn how to overcome them with Hard Disk Drive: Mechatronics and Control. Beginning with an overview of history, components, operating principles, and industry trends, the authors examine the design and manufacturing challenges. They start with the head positioning servomechanism followed by the design of the actuator servo controller, the critical aspects of spindle motor control, and finally, the servo track writer, a critical technology in hard disk drive manufacturing. The book compares various design approaches for both single- and dual-stage servomechanisms and illustrates the discussion with numerous examples and figures.
