| Abstract

:
|
This book is a comprehensive text on the theory of the magnetic recording process. It gives the reader a fundamental, in-depth understanding of all the essential features of the writing and retrieval of information for both high density disk recording and tape recording. The material is timely because magnetic recording technology is currently undergoing rapid advancements in systems capacity and data rate. A major contribution to the growth in magnetic recording technology is the recent development of advanced thin film materials for both recording media and transducers. In addition, sophisticated signal processing schemes are being implemented in order to achieve ultra large recording densities as well as high data transfer rates. A comprehension of the basic physics and engineering aspects of magnetic recording is essential if these developments are to be understood and to be utilized in the design of future systems. This text gives a thorough grounding in four basic areas of magnetic recording: structure and fields of heads and media, the replay process, the recording process, and medium noise analysis. In addition to these fundamental issues, key systems questions of non-linearities and overwrite are also discussed. A complete chapter is devoted to the emerging technology of magnetoresistive heads. A parallel treatment of time and frequency response is given to facilitate the understanding and evaluation of signal processing schemes. Using the information presented in this text, the reader should be able to design and analyze key experiments for head and medium evaluation and for overall system testing. This text, which is unique in its scope, will be valuable for both senior undergraduates and graduate students taking courses in magnetic recording. It will also be of value to research-and-development scientists in the magnetic recording industry. An important element of the book is the inclusion of a large number of homework problems. The author assumes that the reader has had basic introductory courses in physics, in electricity and magnetism, and in applied mathematics.
