A method of controlling an optical disc drive to drive a multi-layer optical disc includes acquiring actual optimal aberration correction positions of a first layer and a second layer of the multi-layer optical disc while a position of an aberration correction unit is changed, positioning the aberration correction unit at an intermediate point between the aberration correction position of the first layer and the aberration correction position of the second layer, performing a layer jump from the first layer to the second layer of the optical disc, and positioning the aberration correction unit at the aberration correction position of the second layer.
