The book begins with the basics of magnetism and recording technology, setting the stage for the following chapters on existing methods and related research topics. These chapters focus on perpendicular recording media to underscore the current trend of hard disk media; read sensors, with descriptions of their fundamental principles and challenges; and write head, which addresses the advanced concepts for writing data in magnetic recording. Two chapters are devoted to the highly challenging area in hard disk drives of tribology, which deals with reliability, corrosion, and wear-resistance of the head and media. Next, the book provides an overview of the emerging technologies, such as heat-assisted magnetic recording and bit-patterned media recording. Non-volatile memory has emerged as a promising alternative storage option for certain device applications; two chapters are dedicated to non-volatile memory technologies such as the phase-change and the magnetic random access memories. With a strong focus on the fundamentals along with an overview of research topics, Developments in Data Storage is an ideal reference for graduate students or beginners in the field of magnetic recording. It also serves as an invaluable reference for future storage technologies including non-volatile memories.

Data Storage TechnologiesK.L.JAMESInformation has become very costly and indispensable in recent times. Information is present everywhere and is created continuously. It can be commonly seen that organizations are struggling hard for properly and effectively managing the huge volumes and varieties of information flowing through business systems, as the quantum of information is increasing with the passing of time. The use of information in its originally created form and style creates several difficulties and hence this is not done. The essentially required data is extracted from the huge information pile by employing suitable methods and appropriate technologies. The extracted data is properly stored for archiving and effective retrieving. Storing all the routine information dealt by organizations is costly and difficult. With the changes in requirements and technologies, businesses are constantly exploring and experimenting new methods for properly storing and effectively managing data. The ageing storage architectures and technologies are found too costly in terms of cost and time spent for effective data storage and management. Newer technologies such as converged and hyper converged infrastructures, public and private clouds, scaled up and scaled out devices, flash technology and software defined solutions are making the storage efficient and better. The text book Data Storage Technologies discusses the different concepts associated with data storage and the technologies used as well as the trends and practices followed in the designing and managing of efficient data storage systems. The book is targeted for students undergoing courses in data storage systems as well as for professionals working in related fields. The objective of the book is to introduce to the reader the basic concepts associated with data storage, steps necessary for designing well suited data storage solutions and the effective ways of using new technologies for data storage and management. Starting with an introductory chapter dealing with the basic concepts, the book progresses to discuss new topics like storage virtualization and cloud storage. The end chapter worksheets and short answer questions act as resources for self assessment and to test the new knowledge gained from each chapter of the book. Elegant and simple style of presentation makes reading of this book a pleasant experience. The book will be found highly acceptable to those who are interested to get acquainted with the latest and the newest trends associated with data storage technologies.

In recent years, libraries have embraced new technologies that organize and store a variety of digital information, such as multimedia databases, digital medical images, and content-based images. Modern Library Technologies for Data Storage, Retrieval, and Use highlights new features of digital library technology in order to educate the database community. By contributing research from case studies on the emerging technology use in libraries, this book is essential for academics and scientists interested in the efforts to understand the applications of data acquisition, retrieval and storage.

Although there are already some books published on Big Data, most of them only cover basic concepts and society impacts and ignore the internal implementation details-making them unsuitable to R&D people. To fill such a need, Big Data: Storage, Sharing, and Security examines Big Data management from an R&D perspective. It covers the 3S desi

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 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.

Holographic Data Storage: From Theory to Practical Systems is a primer on the design and building of a holographic data storage system covering the physics, Servo, Data Channel, Recording Materials, and optics behind holographic storage, the requirements of a functioning system, and its integration into "real-life" systems. Later chapters highlight recent developments in holographic storage which have enabled readiness for commercial implementation and discuss the general outlook for the technology, including the transition from professional to consumer markets and the possibilities for mass reproduction.

With the evolution of digitized data, our society has become dependent on services to extract valuable information and enhance decision making by individuals, businesses, and government in all aspects of life.
