Abstract
A method and apparatus are disclosed for positioning a transducing apparatus relative to a rotating storage medium through the use of an externally commutated positioning apparatus under control of a processing element. In addition, a control method is disclosed which includes an initial determination of salient parameters associated with the apparatus. Positioning of the transducing apparatus is achieved through a plurality of control modes which are responsive to the determined parameters. In addition, the accuracy with which position of the transducing apparatus is determined varies among the modes with the remaining distance yet to traverse to a desired destination position.
