A comprehensive, easy-to-use guide to the fundamentals and applications of magnetism As magnetic recording technology continues to evolve at a rapid pace-in digital data storage as well as video and audio applications-there is a growing need for a basic primer to help explain advances in the field. Written by industry expert R. Lawrence Comstock, this immensely useful guide combines an introductory treatment of the physics and material science of magnetism with clear, thorough, up-to-date coverage of magnetic recording systems and their components. From basic magnetic properties to the fabrication of magnetic mate-rials to the magnetic recording process, Dr. Comstock examines in detail both theory and applications, reinforces concepts with real-world data, and provides insight into new and emerging technologies. Key topics include: * The ferromagnetism of the transition metals * Properties of ferromagnetic thin films * The state of the art of digital magnetic recording technology * Magnetic recording heads, including magnetoresistive and giant magnetoresistive heads * Recording media in disk drive technology An indispensable resource for engineers and scientists working on the development and manufacturing of magnetic recording technologies, Introduction to Magnetism and Magnetic Recording also features extensive tables of the properties of magnetic materials, 30 photographs, and more than 200 graphs. Dr. Comstock retired as a senior technical staff member from IBM after more than two decades of service. He was a Vice President of Advanced Technology at Maxtor Corporation for three years.

Magnetic random-access memory (MRAM) is poised to replace traditional computer memory based on complementary metal-oxide semiconductors (CMOS). MRAM will surpass all other types of memory devices in terms of nonvolatility, low energy dissipation, fast switching speed, radiation hardness, and durability. Although toggle-MRAM is currently a commercial product, it is clear that future developments in MRAM will be based on spin-transfer torque, which makes use of electrons’ spin angular momentum instead of their charge. MRAM will require an amalgamation of magnetics and microelectronics technologies. However, researchers and developers in magnetics and in microelectronics attend different technical conferences, publish in different journals, use different tools, and have different backgrounds in condensed-matter physics, electrical engineering, and materials science. This book is an introduction to MRAM for microelectronics engineers written by specialists in magnetic materials and devices. It presents the basic phenomena involved in MRAM, the materials and film stacks being used, the basic principles of the various types of MRAM (toggle and spin-transfer torque; magnetized in-plane or perpendicular-to-plane), the back-end magnetic technology, and recent developments toward logic-in-memory architectures. It helps bridge the cultural gap between the microelectronics and magnetics communities.

The advent of the internet age has produced enormous demand for in creased storage capacity and for the consequent increases in the amount of information that can be stored in a small space. While physical and media improvements have driven the majority of improvement in modern storage systems, signal processing and coding methods have increasing ly been used to augment those improvements. Run-length-limited codes and partial-response detection methods have come to be the norm in an industry that once rejected any sophistication in the read or write pro cessing circuits. VLSI advances now enable increasingly sophisticated signal processing methods for negligible cost and complexity, a trend sure to continue even as disk access speeds progress to billions of bits per second and terabits per square inch in the new millennium of the in formation age. This new book representing the Ph. D. dissertation work of Stanford's recent graduate Dr. Zining Wu is an up-to-date and fo cused review of the area that should be of value to those just starting in this area and as well those with considerable expertise. The use of saturation recording, i. e. the mandated restriction of two-level inputs, creates interesting twists on the use of communica tion/transmission methods in recording.

"The first magnetic recording device was demonstrated and patentedby the Danish inventor Valdemar Poulsen in 1898. Poulsen made amagnetic recording of his voice on a length of piano wire. MAGNETICRECORDING traces the development of the watershed products and thetechnical breakthroughs in magnetic recording that took placeduring the century from Paulsen's experiment to today's ubiquitousaudio, video, and data recording technologies including taperecorders, video cassette recorders, and computer harddrives. An international author team brings a unique perspective, drawnfrom professional experience, to the history of magnetic recordingapplications. Their key insights shed light on how magneticrecording triumphed over all competing technologies andrevolutionized the music, radio, television and computerindustries. They also show how these developments offeropportunities for applications in the future. MAGNETIC RECORDING features 116 illustrations, including 92photographs of historic magnetic recording machines and theirinventors." Sponsored by: IEEE Magnetics Society

Introduction to Magnetic Materials, 2nd Edition covers the basics of magnetic quantities, magnetic devices, and materials used in practice. While retaining much of the original, this revision now covers SQUID and alternating gradient magnetometers, magnetic force microscope, Kerr effect, amorphous alloys, rare-earth magnets, SI Units alongside cgs units, and other up-to-date topics. In addition, the authors have added an entirely new chapter on information materials. The text presents materials at the practical rather than theoretical level, allowing for a physical, quantitative, measurement-based understanding of magnetism among readers, be they professional engineers or graduate-level students.
