マイクロマグネティクスの磁気記録への応用III 記録へッドへの適用( 1 )Applications of Micromagnetics to Magnetic Recording III Recording Field and Magnetization Analysis of Recording Write Heads (1)

摘要

Analysis of the recording field and magnetization of recording write heads is surveyed as part of a series of articles entitled Applications of Micromagnetics to Magnetic Recording." The present article discusses write head modeling with various methods, the necessity of self-consistent analysis, and speed-up of Landau- Lifshitz-Gilbert (LLG) micromagnetic caluculations.
