摘要： A tracking controller includes a tracking error detecting section and a tracking control section. The tracking error detecting section generates and outputs a tracking error signal that represents how much the focal point of a light beam has shifted from a target track on a storage medium. The tracking control section generates a drive signal in response to the tracking error signal so as to move the light beam such that the focal point of the light beam is located right on the target track. The gain of at least one of the tracking error signal and the drive signal is switched depending on whether or not the focal point of the light beam is located on a recorded area of the storage medium on which data has already been written.

摘要： Before data is recorded in an optical disc, an optimum recording power is calculated in an inner peripheral part and in an outer peripheral part of the optical disc based on OPC learning. Before the data is recorded in the optical disc, the optimum recording power is calculated in at least an intermediate part between the inner peripheral part and the outer peripheral part of the optical disc based on the OPC learning. Then, a correlation between position shift amounts in the inner peripheral part, the outer peripheral part and the intermediate part along a radial direction of the optical disc and the optimum recording powers calculated in the respective parts is calculated. The optimum recording power in a current recording part is set based on the correlation when the data is recorded, and laser drive control is executed with the set optimum recording power so that the data is recorded in the optical disc.
