Magnetic data storage can be viewed as a data communication system. This is not a sUlprising view, considering that data storage is essentially the transfer of data between different times. The past decade has indeed seen rapidly growing interest in applying improved coding and detection techniques to magnetic data storage, a traditional approach to enhance performance of communication channels. Since its inception in the 1930's, the magnetic recording industry has achieved impressive progress in data capacity. This has been made possible mainly by innovations and advances in heads and media design. However, as the demand for higher storage capacity continues in the modem information era, a need arises to explore other possibilities to help meet the ever-growing demand. Advanced coding and detection are one such possibility, providing an efficient, cost-effective means to increase data capacity. In fact, with the advent of modem Ie technology which has enabled real-time implementation of increasingly complex signal processing algorithms, advanced coding and detection are rapidly becoming a major issue in the development of improved data storage products. While there have been remarkable advances in recent years in the areas of both coding and detection for data storage, this book focuses only on data detection, or the processing of readback waveforms to reproduce stored data, in conjunction with the traditional modulation coding method called run length-limited or (d,k) coding.

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.

The explosive increase in information and the miniaturization of electronic devices demand new recording technologies and materials that combine high density, fast response, long retention time and rewriting capability. As predicted, the current silicon-based computer circuits are reaching their physical limits. Further miniaturization of the electronic components and increase in data storage density are vital for the next generation of IT equipment such as ultra high-speed mobile computing, communication devices and sophisticated sensors. This original book presents a comprehensive introduction to the significant research achievements on high-density data storage from the aspects of recording mechanisms, materials and fabrication technologies, which are promising for overcoming the physical limits of current data storage systems. The book serves as an useful guide for the development of optimized materials, technologies and device structures for future information storage, and will lead readers to the fascinating world of information technology in the future.

In recent years considerable effort has been expended on high density digital recording. The goal has been to increase the data storage per unit length of tape, usually focused on a fixed track width. The present investigation advances the thesis that optimum data storage per square of tape is achieved by increasing the number of tracks, rather than the storage per track. An experimental method for the determination of the best operating point is described, and data is presented for Non-Return-to-Zero-Level (NRZ-L), Manchester and Miller codes for an ideal tape recorder, and also for an actual tape recorder.

In the big data era, data storage is one of the cores in the whole information chain, which includes production, transfer, sharing, and finally processing. Over the years, the growth of data volume has been explosive. Today, various storage services need memories with higher density and capacity. Moreover, information storage in the big data applications should be green, safe, and long life. The storage density of memories was largely enhanced in recent years because of the rapid development of nanotechnology. The minimum feature size of optical, magnetic, and electrical memories is already at the nanometer scale. Furthermore, the interdisciplinary cooperation of nanotechnology can facilitate the development of data storage technology to achieve higher operation speed, lower power consumption, and increased retention time. This book compiles the cutting-edge research progress of nanometer-scale data storage. The main topics covered include optical memory, random access memory, magnetic memory, and hybrid memory. The text emphasizes more practical methods for data storage development and applications.

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.

Microcantilevers for Atomic Force Microscope Data Storage describes a research collaboration between IBM Almaden and Stanford University in which a new mass data storage technology was evaluated. This technology is based on the use of heated cantilevers to form submicron indentations on a polycarbonate surface, and piezoresistive cantilevers to read those indentations. Microcantilevers for Atomic Force Microscope Data Storage describes how silicon micromachined cantilevers can be used for high-density topographic data storage on a simple substrate such as polycarbonate. The cantilevers can be made to incorporate resistive heaters (for thermal writing) or piezoresistive deflection sensors (for data readback). The primary audience for Microcantilevers for Atomic Force Microscope Data Storage is industrial and academic workers in the microelectromechanical systems (MEMS) area. It will also be of interest to researchers in the data storage industry who are investigating future storage technologies.
