Abstract

Magnetic storage is the most important technology for data recording and has progressed very rapidly in the last half century. Although it has reached a high level of refinement, it is still evolving and experimenting new proposals. Random access magnetic memories have been developed or proposed, using the magnetization states of magnetic nanodisks and nanorings ; other solutions include the encoding of information onto a string of magnetic domains, or of skyrmions , in magnetic strips and nanowires . This chapter describes the main concepts behind magnetic recording, aspects of the evolution of the recording technologies, and the current challenges faced by this field to continue its capacity expansion.
