Abstract

For perpendicular magnetic recording system, we suggest the modeling scheme combining finite element method and the fine field analysis. We did not use the Karlqvist head field but simulated a head field by the finite element method with precise simulation. For this purpose, we developed a Laplace program to calculate the head field at micromagnetic domains. We simulated the write process for a conventional head with a single layer perpendicular media and compared magnetic force microscopy images of simulated written bit patterns and tested patterns
