Book Description
The hard disk drive is one of the finest examples of the precision control of mechatronics, with tolerances less than one micrometer achieved while operating at high speed. Increasing demand for higher data density as well as disturbance-prone operating environments continue to test designers' mettle. 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 hard disk drive history, components, operating principles, and industry trends, the authors thoroughly 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. By comparing various design approaches for both single- and dual-stage servomechanisms, the book shows the relative pros and cons of each approach. Numerous examples and figures clarify and illustrate the discussion. Exploring practical issues such as models for plants, noise reduction, disturbances, and common problems with spindle motors, Hard Disk Drive: Mechatronics and Control avoids heavy theory in favor of providing hands-on insight into real issues facing designers every day.

Book Description
The series Advances in Industrial Control aims to report and encourage technology transfer in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. New theory, new controllers, actuators, sensors, new industrial processes, computer methods, new applications, new philosophies , new challenges. Much of this development work resides in industrial reports, feasibility study papers and the reports of advanced collaborative projects. The series offers an opportunity for researchers to present an extended exposition of such new work in all aspects of industrial control for wider and rapid dissemination. Hard disk drive systems are ubiquitous in today’s computer systems and the technology is still evolving. There is a review of hard disk drive technology and construction in the early pages of this monograph that looks at the characteristics of the disks and there it can be read that: “bit density... continues to increase at an amazing rate”, “spindle speed... the move to faster and faster spindle speeds continue”, “form factors... the trend...is downward... to smaller and smaller drives”, “performance... factors are improving”, “redundant arrays of inexpensive disks... becoming increasingly common, and is now seen in consumer desktop machines”, “reliability... is improving slowly... it is very hard to improve the reliability of a product when it is changing rapidly” and finally “interfaces... continue to create new and improved standards... to match the increase in performance of the hard disks themselves”.

Book Description
The true story behind the rise of a tyrannical genius, how he transformed an industry, and why everyone is out to get him.In this fascinating expos , two investigative reporters trace the hugely successful career of Microsoft founder Bill Gates. Part entrepreneur, part enfant terrible, Gates has become the most powerful -- and feared -- player in the computer industry, and arguably the richest man in America. In Hard Drive, investigative reporters Wallace and Erickson follow Gates from his days as an unkempt thirteen-year-old computer hacker to his present-day status as a ruthless billionaire CEO. More than simply a "revenge of the nerds" story though, this is a balanced analysis of a business triumph, and a stunningly driven personality. The authors have spoken to everyone who knows anything about Bill Gates and Microsoft -- from childhood friends to employees and business rivals who reveal the heights, and limits, of his wizardry. From Gates's singular accomplishments to his equally extraordinary brattiness, arrogance, and hostility (the atmosphere is so intense at Microsoft that stressed-out programmers have been known to ease the tension of their eighty-hour workweeks by exploding homemade bombs), this is a uniquely revealing glimpse of the person who has emerged as the undisputed king of a notoriously brutal industry.

Book Description
On June 24, 2012, Dr. Shane Truman Todd, a young American engineer, was found hanging in his Singapore apartment, just a week before his scheduled return to the United States. Although Shane had repeatedly expressed apprehension about his work with a Chinese company and fear his life was being threatened, authorities immediately ruled his death a suicide. His family initially didn’t know what to believe. However, upon arriving in Singapore, they realized the evidence suggested not suicide, but murder. Shane’s family later discovered that what they thought was a computer speaker was actually an external hard drive with thousands of files from Shane’s computer. The information in those files transformed this story from a tragic suicide to an international saga of mystery, deceit, and cover-up, involving three countries. “Hard Drive: A Families Fight against Three Countries” is the captivating story of Shane’s mysterious death and his family’s grueling battle to reveal the truth against powerful forces that have sought to conceal, destroy, or discredit evidence indicating homicide. This story, which is told from the unique perspective of Shane’s mother, Mary, recounts the family’s painful, arduous, and unwavering endeavor to reveal the truth about what happened to Shane Todd in Singapore
