摘要： An optical disk apparatus which can carry out tilt control using a signal of a focus control system so as to improve the recording/reproducing performance of an optical disk. The optical disk apparatus includes a motor which rotates the optical disk, an optical pickup which reads at least information from the optical disk being rotated by the motor, a first memory which uses information of a rotation angle of the optical disk from the optical pickup as an address, a second memory which stores an offset by which information stored in the first memory should be shifted and then read, and a control portion which reads the information stored in the first memory after shifting the information by the offset stored in the second memory and which carries out tilt control using the read information.
