| Abstract: | Advancements in perpendicular magnetic recording media were reviewed. This article focused mainly on the conventional perpendicular media, tilted perpendicular media, and thermal assistant perpendicular media. As for the conventional media, we reviewed the advancements in coercivity, nucleation field, grain size, size distribution, exchanged decoupling interaction, and so on. The other two kinds of media have been developed to solve the problems caused by writing ability of magnetic writer at ultra-high recording density. The development, advancements, and advantages of the exchange coupled composite (ECC) media were introduced. Meanwhile, only mechanism of thermal assistant recording media was described. |
