Short-Wavelength Magnetic Recording

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."e;The scope and mathematical rigour of this book can only be compared with W.K. Westmijze's 1953 landmark "e;Studies in Magnetic Recording"e;"e;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."e; John C.
