Abstract
Controlling positions of storage media heads is disclosed. An example storage media head position controller includes a position error filter to filter a media head position error based on a target position for a storage media head relative to a storage medium and a present media head position to generate a position signal, and a media speed monitor to modify an integration factor in the position error filter based on a media speed to adjust a phase margin of the position control loop.
