An apparatus and method for controlling an optical disk device performs a disk loading and unloading operation based on at least one driving signal containing multiple pulses of different widths. The pulses are applied to control a motor to unclamp the disk relative to a spindle. Because the signal is formed from multiple pulses of different widths, the unclamping operation is performed with little or no shock forces and as a result the disk is ejected without damage and without being dislodged from the device.
