Available in PDF, EPUB and Kindle. Book excerpt: 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”.

The book is designed to provide a better grounding in the theory underlying several important areas of control. It is hoped the book will help the reader to apply otherwise abstruse ideas of nonlinear control in a variety of real systems.
Download or read book Hard Disk Drive written by Abdullah Al Mamun and published by CRC Press. This book was released on 2017-12-19 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Ultra High Density Magnetic Recording written by Gaspare Varvaro and published by CRC Press. This book was released on 2016-03-30 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today magnetic recording is still the leading technology for mass data storage. Its dominant role is being reinforced by the success of cloud computing, which requires storing and managing huge amounts of data on a multitude of servers. Nonetheless, the hard-disk storage industry is presently at a crossroads as the current magnetic recording technologies are unable of achieving densities beyond 1 Tbit/in2. Pushing the recording density in the terabit regime requires new storage materials, novel recording schemes, and media designs in order to solve signal-to-noise ratio, thermal stability, and writability issues. In this book, worldwide experts from universities, public research institutions, and industry collaborate to illustrate the most recent progresses in magnetic recording from the media perspective and to highlight the future prospects of the technology. Theoretical, experimental, and technological aspects are covered in a clear and comprehensive way, making the book a useful reference for final-year undergraduates, postgraduates, and research professionals in the magnetic recording area. The first two chapters introduce the fundamentals of magnetism and magnetic recording and are useful to guide the reader in the chapters that follow. Chapters 3, 4, and 5 focus on the materials for conventional perpendicular recording media, next-generation recording media, and exchange-coupled composite media. The most promising technologies for next-generation magnetic recording, i.e., energy assisted and bit-patterned recording, are extensively treated in chapters 6 and 7, while chapter 8 covers the techniques and protocols for magnetic characterization of recording media. Finally, chapter 9 gives an overview of the emerging classes of magnetic memories.

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. From time to time a particular practical control problem emerges as a challenge to the design capabilities of the control community. One example has been the activated sludge process in wastewater systems where the process is highly nonlinear and measurements are few. A second example is the hard disk drive servo system. These widely used systems are critical to the operation of modem computing devices. They are nonlinear and demand a high-precision control system for the operations of track seeking and track following. There are also alternative actuation systems available to achieve these objectives. In this Advances in Industrial Control monograph B.M. Chen, T.H. Lee and V.

Book excerpt: Advances in Information Storage Systems (AISS), volumes 9 & 10, are special volumes which contain selected papers regarding not only information storage but also information equipment in general and related technologies. The papers were presented at the International Conference on Micromechatronics for Information and Precision Equipment (MIPE '97). MIPE '97 was held in Tokyo, Japan, from 20 to 23 July 1997, as one of the memorial events of the Centennial Grand Congress of the Japan Society of Mechanical Engineers. Information and precision equipment is fast-changing high technology, and is necessary for the development of an international multimedia society and essential for the innovation of conventional machines as well as the creation of new sophisticated machines for future medical, biological and cosmic industries in the 21st century. Information and precision equipment can improve their performances by analyzing, designing, fabricating, controlling and then utilizing a smaller and smaller world in space and time. Micromechatronics is not only a major interdisciplinary engineering but also the principle of innovation in such machines. In the light of this, the scope of MIPE '97 ranged from the micromechanics and micromechatronics of information storage, input/output devices, and precision equipment to microtechnologies related to information equipment. The papers in AISS special volumes are mainly related to information storage, particularly magnetic recording storage. But some of them are related to printer, paper-feeding-mechanism and micromachine technologies, which will directly or indirectly contribute future information devices. The papers contained in this series are of international archival quality and are refereed according to rigorous journal standards. Volume 9 contains papers on the mechanics and tribology of magnetic recording storage systems (mainly hard disk drives), while papers on the micromechatronics of the head-positioning system in magnetic disk storage are compiled in Volume 10 together with papers on optical disk storage and others.
