Short-wavelength magnetic recording presents a series of practical solutions to a wide range of problems in the field of magnetic recording. It features many new and original results, all derived from fundamental principles as a result of up-to-date research. A special section is devoted to the playback process, including the calculations of head efficiency and head impedance, derived from new theorems. Features include: A simple and fast method for measuring efficiency; a simple method for the accurate separation of the read and write behaviour of magnetic heads; a new concept - the bandpass head. Other types of head covered include: the metal-in-gap head; the amarphous head; the thin-film head; the magneto-resistive head; and probe-type heads for perpendicular recording. The introduction includes an invaluable historical summary of magnetic recording, and the book also features an extensive subject index, complete author index, and a glossary of symbols. "The scope and mathematical rigour of this book can only be compared with W.K. Westmijze's 1953 landmark "Studies in Magnetic Recording" "The easy writing style (renders) the mathematical treatments readily understandable as physical propositions... A careful study of this book cannot help but provide the reader with the most profound insights into the limits of short-wavelength recording." John C. Mallinson, Center for Magnetic Recording Research, University of California, San Diego, USA.

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.

The book provides both the theoretical and the applied background needed to predict magnetic fields. The theoretical presentation is reinforced with over 60 solved examples of practical engineering applications such as the design of magnetic components like solenoids, which are electromagnetic coils that are moved by electric currents and activate other devices such as circuit breakers. Other design applications would be for permanent magnet structures such as bearings and couplings, which are hardware mechanisms used to fashion a temporary connection between two wires. This book is written for use as a text or reference by researchers, engineers, professors, and students engaged in the research, development, study, and manufacture of permanent magnets and electromechanical devices. It can serve as a primary or supplemental text for upper level courses in electrical engineering on electromagnetic theory, electronic and magnetic materials, and electromagnetic engineering.

As Lord Kelvin said, "Fourier's theorem is not only one of the most beautiful results of modern analysis, but it may be said to furnish an indispensable instrument in the treatment of nearly every recondite question in modern physics." This has remained durable knowledge for a century, and has extended its applicability to topics as diverse as medical imaging (CT scanning), the presentation of images on screens and their digital transmission, remote sensing, geophysical exploration, and many branches of engineering. Fourier Analysis and Imaging is based on years of teaching a course on the Fourier Transform at the senior or early graduate level, as well as on Prof. Bracewell's 1995 text Two-Dimensional Imaging. It is an excellent textbook and will also be a welcome addition to the reference library of those many professionals whose daily activities involve Fourier analysis in its many guises.
