Abstract :
This paper describes the micromagnetic simulation of a single-pole-type (SPT) head for perpendicular magnetic recording. A Landau-Lifshitz-Gilbert (LLG) calculation that treats the whole magnetic material micro-magnetically is performed. The recording fields are investigated for various pole tip structures. It is found that an optimum non zero throat height exists that maximizes recording field strength
