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.Contents:High-Density Magnetic Data Storage (H-M Wu et al.)Optical Data Storage for the Future (W-F Yuan & Y-L Song)High-Density Electrical Data Storage (G-Y Jiang & Y-L Song)Nanoscale Data Storage (J-C Li & Y-L Song)Readership: Advanced undergraduates and graduate students in materials, chemistry, physics, optic/electric engineering and devices science, as well as nonexperts who want to have an overview about current and future developments in information technology; can also be used as a textbook or reference book for advanced undergraduates and graduate students.
