RECORDING APPARATUS, MOTOR CONTROL APPARATUS, AND MOTOR CONTROL METHOD

A motor control apparatus which can improve detection accuracy of control information and stabilize a control system includes a detector for detecting first pulse information which corresponds to the drive speed of a driven object and second pulse information out of phase with the first pulse information; edge detectors for detecting rising edges and falling edges of the detected first pulse information and second pulse information; edge interval measuring units for measuring edge-to-edge periods using the detected rising edges and falling edges; a calibrator for calibrating the measured edge-to-edge periods with a reference period for driving the driven object at constant speed; a corrector for correcting the first pulse information and second pulse information based on the calibration; and a controller for generating control commands to drive the driven object based on the corrected first pulse information and second pulse information.
