A servo wedge on a recording medium for a disk drive includes a gray-code field that stores a micro-jog correction factor for a data track. The micro-jog correction factor compensates for the effect of accumulated track pitch variations. In one embodiment, the radial wedge formed by gray-code fields for adjacent data tracks is a continuous radial wedge similar to the gray-code field used for encoding track numbers.
