1. A method, comprising: obtaining a plurality of data density values as a function of a corresponding plurality of bit error rates; obtaining a plurality of track density values as a function of a corresponding plurality of bit error rates; determining a data density/track density correlation between the plurality of data density values and the plurality of track density values for at least one Sector Error Rate (SER); and determining a data density capability value and a track density capability value that provides an areal density capability (ADC) value that satisfies one or more predefined criteria using the data density/track density correlation.
