Abstract
PURPOSE:To compensate the erroneous detection of a position error signal, by constituting the titled system so that a driving signal value calculating means executes the recalculation of a driving signal value by setting an output value of a position error counting-back means as a position error, when an output means has outputted a predictive driving signal value as a driving signal of the present sector. CONSTITUTION:A position error signal (e) for showing a difference between a target position and the present position of a magnetic head is obtained at every sector, and based on this position error (e), a driving signal calculating means 1 calculates a driving signal value u''k+1 to a magnetic head driving mechanism. Also, a driving signal storage means 2 stores a driving signal value of every sector. A first and a second subtracting means 3a, 3b, a first and a second adding means 4a, 4b and an averaging means 5 obtain a predictive driving signal value of the next sector of the present sector by them. A comparing means 6 compares an output of the averaging means 5 and a driving signal value of the present sector, and when the predictive driving signal value has been set as the driving signal value of the present sector, a position error value counted back by a position error counting-back means 7 is inputted to the driving signal calculating means 1, and the recalculation of the driving signal is executed. In such a way, an erroneous detection of the position error signal can be compensated.
