High density digital magnetic and magneto-optical storage devices are widely used in audio, video, and data processing information technology, as well as in CAD/CAM computer systems. These widespread uses generate a continually increasing demand for both increased information storage densities and capacities, and for reduced access times. Hence, the materials engineering of high density storage media, with a high signal to noise ratio, and the associated design of sophisticated read and write heads, form the basis of major technological research. This research is especially complex because, ideally, the recorded information should be both erasable and, at the same time, secure and accessible over periods of many decades. As a result, research on these complex problems requires a multidisciplinary approach which utilizes the expertise in such widely differing fields as organic, inorganic, and solid state chemistry, metallurgy, solid state physics, electrical and mechanical engineering, and systems analysis. Often, further research specialization is necessary in each of these different disciplines. For instance, solid state physics and chemistry address the problems of crystallographic structure and phase diagram determination, magnetism, and optics, but more advanced research methods, such as high resolution electron microscopy and electronic band structure calculations, are necessary to understand the microstructure of particulate recording media or the electronic spectra of magneto-optical recording media.

This book deals with many aspects of high density digital recording. It begins with very basic concepts in magnetism and magneto-optics, then continues with the synthesis and physical properties of recording media, thin films and particulate media. More technological aspects of recording heads and their contact with the recording media are also discussed in subsequent chapters. The second part of the book is devoted to the magneto-optical properties of various recording media and to the engineering of magneto-optical recording.

Design, modifications, test, evaluation and analysis were made on a predistortion encoder, record equalizer, HDMR head, playback preamplifier, delay modulation detector, and computer tape transport. Performance and performance limits were analyzed and applied to the modulation and coding, tape and head-tape interface, and magnetic heads technologies. (Author).
