Patent ID: 7382570

Claim:
A method of controlling seeking of a transducer that is adjacent to a rotatable disk in a disk drive, the method comprising: accelerating the transducer radially across the rotatable disk from an initial track on the rotatable disk toward a destination track on the rotatable disk; estimating a deceleration switching position/velocity point; estimating a maximum deceleration position/velocity point following the deceleration switching position/velocity point; estimating a deceleration current required to decelerate the transducer from a non-zero velocity at the maximum deceleration position/velocity point to zero velocity at the destination track; comparing the estimated deceleration current to a maximum available deceleration current; and responsive to a determination that the current required to decelerate the transducer from the maximum deceleration position/velocity point to the destination track exceeds the maximum available deceleration current, adjusting the estimated deceleration switching position/velocity point.
