Patent ID: 7199966

Claim:
A disk drive comprising: (a) a disk comprising a plurality of tracks; (b) an actuator arm; (c) a head connected to a distal end of the actuator arm; (d) a voice coil motor for rotating the actuator arm about a pivot to actuate the head over the disk; and (d) control circuitry for controlling the voice coil motor during a seek operation to seek the head from a first track to a second track by: computing a first seek time corresponding to a first seek profile; computing a second seek time greater than the first seek time; computing a second seek profile in response to the first seek time, the second seek time, and a scaling factor that accounts for a back EMF voltage generated by the voice coil motor; and controlling the voice coil motor according to the second seek profile to seek the head from the first track to the second track.
