Abstract
A transducer is controlled during seeking based on an acceleration-phase state error. While seeking, the transducer is moved from an initial track to a target track on the disk based on a current command. At least one transducer state relative to the disk is estimated while seeking. At least one transducer state relative to the disk is measured while seeking. An acceleration-phase state error is determined that is indicative of an error between the estimated at least one transducer state and the measured at least one transducer state as the transducer is accelerated toward the target track during the seeking. The current command is generated based on the acceleration-phase state error.
