本文从理论和实验两方面讨论纵向和垂直磁记录的金属薄膜介质的区别,虽然对这两种记录方式的写入过程还不完全清楚。但它们的本质是相似的,现有资料证明,它们的记录特性差别很小,与理论的推断相一致。 This paper discusses the difference between a vertical and a perpendicular magnetic recording of a metal thin film both theoretically and experimentally, although the writing of these two recording methods is not fully understood. However, their nature is similar. The available data prove that their recording characteristics are very different and consistent with the theoretical inference.
