Planar type recording write heads were investigated using a micromagnetic analysis targeting a transfer-rate of 5 GHz. Six different planar head structures with various yoke widths, yoke heights, and coil locations were modeled. Six different conventional single-pole-type (SPT) write heads were also used for comparison. The material characteristics including the exchange constant, anisotropy energy, and Gilbert damping factor were also varied. It was found that the planar heads had a faster high-frequency response, a larger recording field, and a smaller ATE field. In the planar head, the most dominant factor for high transfer-rate recording was the coil location relative to the main pole tip and the return yoke height, while the yoke width was less important. Because the multi-turn coil can be realized with a wide yoke, it is advantageous in the planar head. With regard to the material characteristics, a small Gilbert damping factor was the most effective, while the other material characteristics did not yield significant differences.
