Abstract
A method is disclosed of operating a disk drive, the disk drive comprising a disk having a plurality of tracks, a head, and a closed loop servo system comprising a seek servo loop and a settle servo loop for actuating the head over the disk. The seek servo loop is used to seek the head toward a target track. When the head approaches the target track, the settle servo loop is used to settle the head on the target track in response to a reference signal generated in response to a system inversion of the settle servo loop.
