A disk drive is disclosed comprising a head actuated over a disk comprising a plurality of tracks, and control circuitry operable to seek the head to a target track and settle the head on the target track during a settle time, adapt a settle parameter over an adapting delay of the settle time, wherein the settle parameter is used to settle the head on the target track, and decrease the adapting delay based on a speed that the settle parameter adapts.

A method of generating a lens position detection signal for optical disc apparatus. The signal is generated in a way which provides continuous position information. The signal is also independent of changes in reflectivity on the surface of the optical disc. Moreover, the signal can be calibrated for DC offset due to misalignment and changes in photo-detector output.
