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 immediate future, where perpendicular recording (higher anisotropy, enhanced write fields using a soft underlayer) 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).
