Tilt control method, program, recording medium, and optical disk drive |
摘要 |
A tilt control method controls an inclination of an objective lens to an optical disk in which a track in the shape of a spiral or a concentric circle is formed. The tilt control method comprising steps of recording data to the optical disk, and acquiring, when recording the data to the optical disk, tilt control information for controlling the inclination of the objective lens based on both known compensation information that is defined with a plurality of kinds of signals acquired when reproducing data from a recorded region of the optical disk, and information that is related to an inclination of the objective lens when an amplitude of a tracking error signal is substantially a maximum in a recording region of the optical disk where the data are recorded.
