Zusammenfassung:	The results of both theoretical and experimental studies of some of the key aspects of the recording physics specific to perpendicular media with a soft underlayer are presented. Some of the discussed issues are the material requirements for the preferred soft underlayer design such as the role of magnetic anisotropy, the proper choice of the magnetic moment, and the control of the soft underlayer noise.
