Abstract
A data storage device is disclosed comprising a head actuated over a disk. Data is written to the disk and read from the disk to measure a quality metric. A recording parameter is repeatedly adjusted and the quality metric is measured for each adjustment of the recording parameter. An operating value for the recording parameter is selected that corresponds to a substantially maximum areal density for the disk when the measured quality metric substantially matches a target quality metric.
