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.
