Abstract
Apparatus and method for moving a control object, such as but not limited to a data read/write transducer adjacent a rotatable magnetic recording medium in a data storage system. In accordance with some embodiments, a compensation value is calculated for a baseline friction model which predicts friction in a positioning system. A modified friction model is generated based on the compensation value and the baseline friction model. A control object of the positioning system is moved from an initial position to a final position responsive to a trajectory profile calculated using the modified friction model.
