Abstract:
1. A method of driving an optical disc drive including a loading roller, a loading motor providing power to the loading roller, a power train system transferring power between the loading motor and the loading roller, and a main slider, the method comprising: transporting a disc to a chucking position where a spindle is located, via the loading roller; blocking power from the loading motor to the loading roller via movement of the main slider, in response to transportation of the disc being completed; and chucking the disc on the spindle using the power transmitted from the loading motor, wherein: said blocking of the power stops rotation of the loading roller and prevents rubbing between the loading roller and the disc in a state that chucking of the disc on the spindle is performed, and the movement of the main slider causes the spindle to lift up and down, when the main slider is moved from a first position to a second position of travel, a spring applies an elastic-biasing force against a clutch gear so as to move the clutch gear along its rotational axis to an engagement position in which the clutch gear contacts first and second gears of the power train system and, while in the engagement position, transfers a rotational force between the first gear and the second gear, when the main slider is moved from the second position to the first position of travel, the clutch lever contacts the clutch gear and applies a force opposite to that applied by the spring so as to move the clutch gear along its rotational axis to a non-engagement position in which the clutch gear does not contact the first and second gears of the power train system and thereby inhibits the transfer of rotational force between the first gear and the second gear, the first gear receives motive force from the loading motor, and the second gear conveys motive force to the loading roller.
