本文讨论了形成具有孤立颗粒结构的Co_（80）Pt_（20）薄膜以获得颗粒型垂直介质的优良记录性能。结果表明，该样品的单轴各向异性常数Ku为1.15 × 102（erg/cc），饱和磁化强度Ms为1100（emu/cc）。随着Ru底层厚度的增加，矫顽力Hc显著增加。
This paper discusses the formation of the Co80Pt20 film with isolated grain structure in order to achieve excellent recording performance of the granular-type perpendicular media. Results show that the uniaxial anisotropy constant Ku and saturation magnetization Ms are 1.15times102 (erg/cc) and 1100 (emu/cc), respectively. The coercivity Hc increases significantly by increasing Ru underlayer thickness.
