Abstract
A data storage device is disclosed comprising a head actuated over a disk comprising a plurality of data tracks, wherein the head comprises a write element radially offset from a read element by a writer/reader offset that varies relative to a radial location of the head over the disk. A first radial band (RB) of the data tracks is written from an outer diameter (OD) of the disk toward an inner diameter (ID) of the disk, and a first jog profile is calibrated for the first radial band that compensates for the writer/reader offset. A second RB is written from an ID to an OD, and a second jog profile is calibrated for the second RB that compensates for the writer/reader offset. The first RB is accessed using the first jog profile, and the second RB is accessed using the second jog profile.
