The design of media, heads, positioning systems and data detection and coding techniques for various generations of magnetic recording systems are discussed. We will start with current systems, such as longitudinal hard disc and tape. Next we will discuss the near future, where perpendicular recording (thicker films, higher stray fields) will address the problem of thermal stability. In the third section we will give an outlook on future developments (patterned media, thermally assisted recording, self assembled arrays of nanoparticles and probe storage).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
