Klappentext
The hard disk drive (HDD) is an excellent example of the practical application of precision mechatronics. Hard Disk Drive: Mechatronics and Control describes the control aspects of an HDD, explains difficulties faced by designers, provides solutions, and highlights challenges of future-generation drives. Combining academic interests with practical problems, it provides a problem-oriented approach to the fundamental concepts of control, examines the process involved in the manufacturing of HDDs, and illustrates the application of precision mechatronics in great detail. Mechatronics researchers not working in HDD will find many concepts developed that are useful for problems in their own areas.
