Abstract
A recording head writes data to a recording medium for one or more iterations. Each iteration involves adjusting a linear data density, a track pitch, and a laser power. From the iterations, a selected linear data density, a selected track pitch, and a selected laser power are determined that together achieve a target areal density and are used to write user data to the recording medium during operation of a hard disk drive.
