Abstract:
A method of positioning a transducer over a desired track on a surface of a disc in a disc drive, the disc drive operating based on drive parameters, the transducer being movable relative to the disc drive with a servo motor, the method comprising:(a) applying an acceleration signal to the servo motor to begin radial positioning of the transducer relative to the disc surface;(b) applying a deceleration signal to the servo motor to stop radial positioning of the transducer relative to the disc surface;(c) controlling application of the deceleration signal to the servo motor according to a deceleration curve the deceleration curve being set as a percentage of an estimate of an actual deceleration current; and(d) varying the percentage of the estimate of the actual deceleration current used to set the deceleration curve based on at least one drive parameter and based on a location of the desired track relative to inner and outer radial edges of the disc surface.
