摘要

Dynamic recording fields of single-pole-type (SPT) heads, having main pole tip dimensions of 25 times 25 nm at the air bearing surface (ABS), were investigated using a Landau-Lifshitz-Gilbert (LLG) micromagnetic analysis. The recording performance in combination with continuous media and bit-patterned media (BPM) was discussed for areal densities of 1-2 Tbit/in2 using the results of LLG micromagne...
