Methods of controlling seeking of a transducer that is adjacent to a
rotatable disk in a disk drive are disclosed. The methods may include
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, and
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. The estimated
deceleration current is compared to a maximum available deceleration
current, and responsive to a determination that the current required to
decelerate the transducer from the maximum deceleration point to the
destination track exceeds the maximum available deceleration current, the
estimated deceleration switching point is adjusted. Related disk drive
apparatus are also disclosed.
