摘要： The reflected light amount acquiring process acquires the reflected light amount of a laser beam with which a color changeable layer is irradiated from at least one irradiation position included in a predetermined drawing determination area, where the color changeable layer is formed on a label side of an optical disc and changes in color due to heat or light. The operation process compares the reflected light amount acquired from the at least one irradiation position by the reflected light amount acquiring process with a predetermined threshold value to determine whether or not the drawing determination area is suitable for formation of a visible image.

摘要： An optical disk signal processing unit (200) performs tracking control to control a position of a converging lens (103) of an optical pickup (100) based on a tracking error signal, and a track jump operation to move the converging lens (103) of the optical pickup (100) in a radial direction of an optical disk (500) while the tracking control is stopped. A gain-increase computation section (209) obtains an amount of increase in a loop gain of a tracking control system based on a velocity of eccentricity of the optical disk (500) at the time of the track jump. After the track jump operation, the tracking control is performed in a situation where the loop gain of the tracking control system has been increased by the amount of increase obtained by the gain-increase computation section (209).
