Abstract:
Apparatus and method for compensating for positional indicia misplacements in the positioning of a control object, such as with servo seam misplacements on a data storage device storage medium. An actual position for the control object is determined in relation to a corrected commanded position of the control object and a corrected position error of the control object. The corrected commanded position is determined in relation to a gain error and an actual commanded position, and the corrected position error determined in relation to the gain error and an actual position error. Preferably, an actual position error of the control object is next determined in relation to the actual position, and the control object is moved to reduce the actual position error. The positional indicia preferably comprise AB and CD seams of ABCD servo dibit patterns on a recording surface.
