It is necessary to develop a perpendicular magnetic recording head for the high magnetic field density of the recording region with small magnetic field leakage. This work suggests a topology design of the perpendicular magnetic recording head based on the density method. In order to determine the shape of a magnetic head with the return yoke, the topology optimization method is combined with the finite element method. Obtained results are also compared with results of the previous studies.
