ABSTRACT:
An optical disk drive including a sliding portion, which moves a sub frame upward or downward against a main frame; a sensor, which includes tension members which are provided in both sides of the sliding portion so that the tension members are elastically deformed to apply an additional load to the sliding portion when the sliding portion slides, and stopper members which contact the tension members and elastically deform the tension members when the sliding portion slides; and a controller, which senses a current change of a driving motor when the additional load is applied to the sliding portion, recognizes whether the tray is loaded or unloaded onto or from the main frame, and controls the driving motor.
