Abstract:
A method of controlling an actuator in a disc drive to move a data head from a current track to a destination track to implement an access, the method comprising steps of:(a) determining a first rotational position corresponding to a rotational position of the data head when the access will start; (b) determining a second rotational position corresponding to a rotational position of the data head at a destination of the access; (c) determining an access time required to move the data head from the first rotational position on an initial track to the second rotational position on a destination track using a fastest of a plurality of seek profiles; (d) determining a slower of the plurality of seek profiles which can be used to move the data head from the first rotational position on the initial track to the second rotational position on the destination track within the determined access time; and (e) controlling the actuator using the determined slower of the plurality of seek profiles to implement the access.
