Opis

This book is designed to give the student a fundamental, in-depth understanding of all the essential features of the magnetic recording process for both high density disk and tape recording. The book provides 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. Besides the fundamental issues, key systems questions of nonlinearities, overwrite, side track phenomena, error rate estimates as well as comparisons of MR and inductive heads will be discussed. The student will be able to use the information presented to design and analyze key experiments for head and medium evaluation as well as for overall system performance decisions. A parallel treatment of time and frequency response will enable the student to evaluate signal processing schemes. The book is intended either for senior-year undergraduates or first-year graduates. It assumes that the reader has had basic introductory electrical engineering or physics courses such as electricity and magnetism and applied mathematics.

Recenzje

'The book is a good link between fundamentals of magnetism and electricity and their technical realizations in the field of magnetic recording … of special value to research-and-development scientists in the magnetic recording industry and includes a plenty of recent references in this field.'
