A method and device are provided for controlling movement of an optical pick-up unit. The method includes a) moving the optical pick-up unit toward a target position of an optical disc; b) while the optical pick-up unit is in motion, detecting a load voltage of a driver for moving the optical pick-up unit and detecting a counted value of the driver's output pulses generated as the driver is activated; and c) determining whether the optical pick-up unit having been moved is positioned at a beginning point of the optical disc on the basis of a current load voltage of the driver and the counted value of the drive's output pulses.
