Available in PDF, EPUB and Kindle. Book excerpt: When I started in magnetic recording nearly fifty years ago, it was easy to perceive the common sense of it. There was very little mathematics and every new finding was a source of wonder. I have tried to recapture this spirit with simple explanations, while maintaining a high density of infonnation and cov ering the entire field. This book introduces a novice to magnetic recording and its many branches. It includes reference data for designers and users. Each chapter stands by itself; no prerequisites are essential. For a quick survey, the equations and worked out examples can be disregarded. The magnetic recording art is changing so rapidly that new advances are announced almost every month. These are properly covered by journal articles and manufacturers' catalogs. This book will fulfil its purpose if it gives a back ground for easily comprehending the new advances. I have included subjects and devices not found elsewhere, and some unconventional viewpoints. I would welcome comments from readers. To Jay McKnight I am deeply grateful for important suggestions and helpful comments. I appreciate also the help of BASF, John Boyers, Joseph Dundovic, Charles Ginsburg, Peter Hammar, Yasuo Imaoka, Hal Kaitchuk, Otto Kornei, Harold Miller, Jack Mullin, Jim Novak, Lenard Perlman, Carl Powell, Sidney Rubens, John Shennan, Shigeo Shima, Heinz Thiele, Yoshimi Watanabe and many others; and to my daughter Ruth for typing.

Download or read book Perpendicular Magnetic Recording written by Sakhrat Khizroev and published by Springer Science & Business Media. This book was released on 2006-01-16 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic recording is expected to become core technology in a multi-billion dollar industry in the in the very near future. Some of the most critical discoveries regarding perpendicular write and playback heads and perpendicular media were made only during the last several years as a result of extensive and intensive research in both academia and industry in their fierce race to extend the superparamagnetic limit in the magnetic recording media. These discoveries appear to be critical for implementing perpendicular magnetic recording into an actual disk drive. This book addresses all the open questions and issues which need to be resolved before perpendicular recording can finally be implemented successfully, and is the first monograph in many years to address this subject. This book is intended for graduate students, young engineers and even senior and more experienced researchers in this field who need to acquire adequate knowledge of the physics of perpendicular magnetic recording in order to further develop the field of perpendicular recording.

Download or read book Ultra High Density Magnetic Recording written by Gaspare Varvaro and published by CRC Press. This book was released on 2016-03-30 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today magnetic recording is still the leading technology for mass data storage. Its dominant role is being reinforced by the success of cloud computing, which requires storing and managing huge amounts of data on a multitude of servers. Nonetheless, the hard-disk storage industry is presently at a crossroads as the current magnetic recording technologies are unable of achieving densities beyond 1 Tbit/in2. Pushing the recording density in the terabit regime requires new storage materials, novel recording schemes, and media designs in order to solve signal-to-noise ratio, thermal stability, and writability issues. In this book, worldwide experts from universities, public research institutions, and industry collaborate to illustrate the most recent progresses in magnetic recording from the media perspective and to highlight the future prospects of the technology. Theoretical, experimental, and technological aspects are covered in a clear and comprehensive way, making the book a useful reference for final-year undergraduates, postgraduates, and research professionals in the magnetic recording area. The first two chapters introduce the fundamentals of magnetism and magnetic recording and are useful to guide the reader in the chapters that follow. Chapters 3, 4, and 5 focus on the materials for conventional perpendicular recording media, next-generation recording media, and exchange-coupled composite media. The most promising technologies for next-generation magnetic recording, i.e., energy assisted and bit-patterned recording, are extensively treated in chapters 6 and 7, while chapter 8 covers the techniques and protocols for magnetic characterization of recording media. Finally, chapter 9 gives an overview of the emerging classes of magnetic memories.

Download or read book Tribology and Mechanics of Magnetic Storage Devices written by Bharat Bhushan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1035 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic recording is presently a $50 billion industry. It spans audio, video, and digi tal applications in the form of tapes and disks. The industry is expected to grow by a factor of five or more in the next decade. This growth will be accompanied by dramatic improvements in the technology, and the potential exists for magnetic-recording den sities to improve by at least one order of magnitude! Magnetic-recording process is accomplished by relative motion between a mag netic head and a magnetic medium. Types of magnetic media for digital recording are: flexible media (tapes and floppy disks) and rigid disks. Physical contact between head and medium occurs during starts and stops and hydrodynamic air film develops at high speeds. Hying heights (mean separation between head and medium) are on the order of 0. 1 micrometer comparable to surface roughness of the mating members. Need for higher and higher recording densities requires that surfaces be as smooth as possible and flying heights be as low as possible. Smoother surfaces lead to increased static/ kinetic friction and wear. In the case of magnetic tapes, in order to have high bit capac ity for a given size of a spool, we like to use as thin a tape substrate as possible. Thinner tapes are prone to local or bulk viscoelastic deformation during storage. This may lead to variations in head-tape separations resulting in problems in data reliability.

Download or read book Coding and Iterative Detection for Magnetic Recording Channels written by Zining Wu and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Sound Recording written by David Morton and published by JHU Press. This book was released on 2006-03-10 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did one of the great inventions of the nineteenth century—Thomas Edison's phonograph—eventually lead to one of the most culturally and economically significant technologies of the twentieth and twenty-first centuries? Sound Recording traces the history of the business boom and the cultural revolution that Edison's invention made possible. Recorded sound has pervaded nearly every facet of modern life—not just popular music, but also mundane office dictation machines, radio and television programs, and even telephone answering machines. Just as styles of music have evolved, so too have the formats through which sound has been captured—from 78s to LPs, LPs to cassette tapes, tapes to CDs, and on to electronic formats. The quest for better sound has certainly driven technological change, but according to David L. Morton, so have business strategies, patent battles, and a host of other factors.
