Abstract
A hard disk drive with a voice coil motor controlled by a circuit. The circuit provides a driving current to the voice coil motor to move a head of the drive in a seek routine. The seek routine includes a settle mode that has an initial state and a velocity versus head position eigenvector. The eigenvector is changed to coincide with on the initial state when the seek routine enters the settle mode. Changing the eigenvector to coincide with the initial state induces a head velocity and movement with minimal overshoot or undershoot during the settle mode.
