Three types of perpendicular recording media were compared using simulations. Exchange coupled composite (ECC) type media could support minimum track pitches up to 18 nm less than a single layer medium, allowing significantly higher areal recording densities. The recording performance of all media was highly susceptible to grain-to-grain variations of uniaxial anisotropy Ku and, in the case of ECC media, to variations in the interlayer coupling strength. Areal densities of around 500 Gb/in2 should be achievable using current technologies, higher densities require improved manufacturing tolerances.
