Abstract
PURPOSE: To enable the normal speed control even if the resonance is in existence in the moving mechanism, by constituting the gain of the speed error detection amplifier that it is not constant at acceleration and deceleration area and the gain is smaller as the absolute value of input increases.
CONSTITUTION: The signal 1 from the track counter 16 where the number of scheduled tracks is set, inputs the objective speed signal 4 to the speed error amplifier 5 via the objective speed generating circuit 18. The output 21 accelerates the moving mechanism 9 to the objective speed via the power amplifier 7 and voice coil motor 8. After the integrating signal of the drive current 13 by the integrator 11, position error signal by the differentiator 12, and the speed signal 6 obtained with the synthesis of the position error signal based on the resonance of the mechanism 9 are in agreement with the objective speed signal 4, the data converter group 20 is moved toward the desired track. Accordingly, the resonance during speed control can be prevented.
