Book Description
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.

Book Description
This book presents the latest research in ultrathin carbon-based protective overcoats for high areal density magnetic data storage systems, with a particular focus on hard disk drives (HDDs) and tape drives. These findings shed new light on how the microstructure and interfacial chemistry of these sub-20 nm overcoats can be engineered at the nanoscale regime to obtain enhanced properties for wear, thermal and corrosion protection – which are critical for such applications. Readers will also be provided with fresh experimental insights into the suitability of graphene as an atomically-thin overcoat for HDD media. The easy readability of this book will appeal to a wide audience, ranging from non-specialists with a general interest in the field to scientists and industry professionals directly involved in thin film and coatings research.
