Bit density / kFRPI Fig. 7. Recording characteristics for Co alloy disks. A and B characters represent the data using disks A and B, respectively. using complete perpendicular magnetic anisotropy media, such as an rf sputtered Co-Cr film. The possibility of a perpendicular recording medium is consequently confirmed by using disks A and B whose magnetic films do not show a complete perpendicular magnetic anisotropy (12), such as an rf sputtered film. Finally, it can be concluded that chemically plated Co alloy magnetic film is applicable as a high density perpendicular recording medium
