The present invention provides a recording apparatus which has reduced the speed variation and vibration of the motor.The recording apparatus uses a step motor (106) as a driving source for means for carrying a carriage (105) mounted with recording means or a recording medium (126), and has control means that, on accelerating the step motor (106), controls so that the step motor (106) is driven with a shorter period than the mechanical time constant of the carrying means when the rotary speed of the motor (106) is less than a specified value, and so that the motor (106) is driven with a longer period than the mechanical time constant when the rotary speed of the motor (106) is more than the specified value.
