<P>PROBLEM TO BE SOLVED: To effectively suppress influence of a torque ripple of a motor for a long time period. <P>SOLUTION: This recording apparatus includes the motor as a driving source, a driving means adapted to move a carriage, a detecting means adapted to detect a position of the carriage, a generating means adapted to generate control data for controlling the motor, a correcting means adapted to correct the control data by using correction data which varies in a cycle the same as that of the torque ripple in order to cancel the torque ripple of the motor, an updating means adapted to update phases of the correction data with respect to the respective positions of the carriage, and a computing means adapted to compute a speed change amount of the carriage on the basis of a detection result of the detecting means. The updating means sequentially and preliminarily sets the phases having a plurality of kinds and updates the phases to reduce the speed change mount on the basis of the speed change mount computed for each of the phases preliminarily set by the computing means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
