Synopsis

This book is aims to be a comprehensive source on the physics and engineering of magneto-resistive heads. Most of the material is presented in a nonmathematical manner to make it more digestible for researchers, students, developers, and engineers.

In addition to revising and updating material available in the first edition, Mallinson has added nine new chapters dealing with various aspects concerning spin valves, the electron spin tunneling effect, the electrostatic discharge effects, read amplifiers, and signal-to-noise ratios, making this a completely up-to-date reference.

The previous edition of Magneto-Resistive Heads was the first volume in the new Academic Press series in Electromagnetism edited by Professor Isaak Mayergoyz, who is a well-recognized expert in the field.

About this title

Review:

"This book is particularly valuable for its discussions. With his very good feeling (or better formulated: experience), John Mallinson consistently finds a good balance between evaluating or presenting equations and discussing relationships, methods and schemes for different applications. In addition, this book is very readable and never dull, and, therefore, highly recommmendable!" --READ-WRITE 96-27

From the Back Cover:

The second edition of Magneto-Resistive and Spin Valve Heads: Fundamentals and Applications brings the book up to date, including much new material that was virtually unknown at the time of the first edition.

The book begins with chapters covering the basics of magnetism, magnetic materials, and the writing and inductive reading processes, as well as the anisotropic and giant magneto-resistive effects. The following chapters cover methods used to produce the necessary magnetic biasing fields, the behavior of shielded single-element magneto-resistive heads, and giant magneto-resistive spin valves. The last few chapters deal with the design and performance of anisotropic and giant magneto-resistive heads (AMRHs and GMRHs, respectively) and consider the likely future of colossal magneto-resistive and electron spin tunneling heads. Almost all the AMRH material found in the first edition has been retained but it has been extensively revised and edited to make it relevant to the present-day applications of AMRHs in high-density digital tape recording. Likely designs of giant magneto-resistive spin valves for operation at 100 gigabits/in.2 in hard disk drives are discussed. An appendix provides a listing of the defining equations and a table of conversion factors for cgs-emu and MKS-SI magnetic units.

The material in the book is presented in essentially a nonmathematical manner. The lack of mathematics should not lead the reader to suppose that this is an elementary exposition. Indeed, the aim is to lead the reader in a straightforward fashion to a high level of scientific understanding of magneto-resistive materials and heads, which are now used in every hard disk drive, as well as in digital tape drives for both computer and consumer applications.

The book is intended as a basic reference for electrical engineering students and individuals working in the recording and information storage industries.

Key features:
· AMRM designs for 10 gigabits/in.2 tape recorders
· GMRH spin valves for 100 gigabit/in2 hard disks
· Future prospects in colossal and spin tunneling magneto-resistive heads
· Self-consistent treatment from basic magnetism to the latest spin valve designs
