Abstract

Until some potentially superior technology such as heat assisted magnetic recording becomes practical, several solutions were proposed to extend the magnetic recording performance. Among them, the most promising in this stage of magnetic recording is the recording media comprising monodisperse high-anisotropy nanoparticles in a self-organized patterning. These media have higher thermal stability, delaying the superparamagnetic effect, low noise and higher signal resolution, which, in turn, led to higher areal density and a better signal-to-noise ratio. The self-organized patterned media permit a better control of the film surface, of the uniformity of the composition, of the geometry of constituent nanoparticles and their magnetic easy axis orientation, which led to the improvement of recording properties. Some considerations concerning the modeling of recording and readout processes on these media are also discussed. Understanding the magnetic properties of the patterned media ensures the desired control of the reversal and stability of these systems and is essential in determining their storage potential and in achieving their design..
