Patent ID: 8027228

Claim:
An optical disk device which executes a seek operation to move an irradiation position of a light beam on an optical disk to a track of a target address, the optical disk device comprising: an optical pickup configured to irradiate light on the optical disk; a position controller coupled to the optical pickup and configured to selectively execute, during execution of the seek operation of the target address, one or more multiple track jump operations in which the position controller controls the optical pickup to move the irradiation position of the light beam along a radial direction of an optical disk by an amount corresponding to a plurality of tracks and one or more one-track jump operations in which the position controller controls the optical pickup to move the irradiation position of the light beam along the radial direction of the optical disk by one track depending on a difference between the target address and a current address of the irradiation position of the light beam; and an off-track determination unit which determines an off-track of the irradiation position of the light beam, wherein when the position controller selects and executes a one-track jump operation, the off-track determination unit determines whether an off-track has occurred during the execution of the one-track jump operation, and when it is determined that an off-track has occurred during the execution of the one-track jump operation, the position controller executes the seek operation through the one or more multiple track jump operations so as to skip over an area in which off-track has occurred, without execution of the seek operation through the one or more one-track jump operations.
