Abstract:
A method for radially moving a transducer over a storage surface of a rotating data disk including multiple concentric data tracks, for reducing noise generated during a seek operation from a starting track to a destination track on the disk, the transducer being radially moveable relative to said data tracks by an actuator in proportion to an input signal to the actuator, wherein the transducer is initially accelerated away from the starting track to a radial transition location between the starting track and the destination track, and then decelerated toward the destination track from the transition location, comprising the steps of:(a) detecting a radial location of the transducer in relation to the disk tracks; (b) detecting the distance between the transducer location and the transition location; (c) estimating a time interval for the transducer to traverse the detected distance; and (d) regulating the input signal as a function of the estimated time interval to control the rate of change of the radial velocity of the transducer across the disk.
