Abstract
An exemplary method for selecting data density values (e.g., bits per inch) and track density values (e.g., tracks per inch) for magnetic recording media having variable bit aspect ratios comprises obtaining a plurality of data density values and 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; and determining a data density capability value and a track density capability value that provides an areal density capability value that satisfies one or more predefined criteria (e.g., a substantially maximum areal density capability value) using the data density/track density correlation. A selected data density value and a selected track density value are optionally determined for a given target areal density capability using the data density/track density correlation and the determined data density capability value.
