Abstract:
A disk drive is disclosed comprising a disk including a plurality of tracks, and a head actuated over the disk, wherein the head comprises a read element radial offset from a write element. A jog value corresponding to the radial offset is calibrated by writing data to a plurality of tracks, reading the plurality of written tracks to generate an actual track crossing signal, cross correlating the actual track crossing signal with an ideal track crossing signal to generate a cross correlation signal, and calibrating the jog value in response to the cross correlation signal.
