Popis:	An optimal write process is essential for realizing the high-density potential of perpendicular recording. An analytic Williams–Comstock-type model of transition width is derived, which is based on a linear transition shape. This model is used to explore the effect of system parameters on transition width. In order to preserve high write field gradient during high-speed recording it is essential to have fast head switching. The role of magnon processes in providing high damping for fast switching is discussed and micromagnetic simulation results are presented.
