The present invention provides a recording apparatus wherein recording is performed by reciprocably shifting a carriage on which a recording head is mounted by means of a stepping motor and which comprises a rotational position detection device for detecting a rotational position of a rotor of the stepping motor, and a control unit for performing a closed loop control for the change-over timing of excitation currents to coils of the stepping motor and for the driving speed of the stepping motor, on the basis of the detection signal from the rotational position detection device, and judges whether the initial drive of the stepping motor and the change-over timing are normal, through the control unit.
