Discrete track perpendicular recording media were simulated to determine the optimum conditions for achieving an areal density of 600 Gbits in2. For a 90 nm track pitch the best performance was obtained from a medium with 60 nm land and 80 nm wide write pole. Comparisons with continuous media showed higher on- and off-track signal-to-noise ratio in some discrete track media, mainly due to the absence of erase band noise. Reducing the average grain size narrowed the differences between the two types of media, resulting in almost identical performance for an average grain size of 6 nm.
