Filed: 2007-11-08
Abstract: An optical disc device, a tracking control start method, and a tracking control start program are provided to start the tracking control normally by allowing first and second minimum eccentric speed regions to have opposite eccentric directions. An optical disc device comprises a minimum region detecting part, and a tracking control judging part. The minimum region detecting part detects a first minimum eccentric speed region where the eccentric speed for allowing a track desired to be separated from an objective lens(30) is minimized, on the basis of the frequency of a traverse signal displayed on a tracking error signal by traversing the track via a spot due to the eccentricity of an optical disc(100), when the optical disc is rotated while the objective lens is fixed. The tracking control judging part judges the control condition of the objective lens by a tracking control part, and detects a second minimum eccentric speed region having the eccentric direction opposed to that of the first minimum eccentric speed region, on the minimum region detecting part if the control of the objective lens is not normally executed.
