  • Patent number: 8027228
    Abstract: An optical disk device executes a seek operation to move an irradiation position of light beam on an optical disk to a track of a target address. During execution of a seek operation through a one-track jump operation in which the irradiation position of the light beam is moved along the radial direction of the optical disk by one track, it is determined whether or not off-track of the irradiation position of the light beam has occurred. When it is determined that the off-track has occurred, a seek operation through a multiple track jump operation is executed in which the irradiation position of the light beam is moved along the radial direction of the optical disk by an amount corresponding to a plurality of tracks.
