In the big data era, data storage is one of the cores of the information chain from production to processing, sharing, and application. To promote and develop information technology, the performance of data storage devices and systems should be increased. The recording density of memories has largely increased in recent years because of the rapid development of nanotechnology. A minimum feature size of optical, magnetic, and electrical memories is already at the nanometer scale.
This book compiles the cutting-edge research progress made in the field of nanometer-scale data storage by several famous Chinese scientists in the information storage field. The main topics covered include optical memory, random access memory, magnetic and hybrid memory, and so on. Emphasis has been put on more practical techniques for data storage developments and applications. The book presents the authors’ thoughts on information storage in the present and the future. It provides the basic knowledge and techniques related to data storage at the nanoscale that will be useful for students, researchers, and engineers in this field.
