Abstract: In this thesis, we investigate the high density magnetic recording schemes with micromagnetic modeling. In the first part of our thesis, we study the surface anisotropy effect of different granular structures on the minimum grain sizes required for thermally stable FePt grains. We conclude that rectangular grains can be more closely packed as compared to circular and hexagonal gains. Besides, the effect of surface anisotropy on the switching field strength required has also been investigated. In the second part of our thesis, we investigate the performance of microwave-assisted magnetic recording scheme which is applied to segmented perpendicular media. Our study aims to understand the assisted switching field behavior with respect to the property of segmented perpendicular media. Our results indicate that the required assisted frequency of microwave field is not sensitive to the inter-segment exchange coupling of segmented perpendicular media.
