  • Patent number: 8238206
    Abstract: The optical disk device includes a generation means and a LC servo means. The generation means generates a lens error signal based on an electrical signal output from a pickup head. After amplifying the lens error signal with a predetermined gain, the generation means outputs the lens error signal. The LC servo means performs lens center servo control based on the lens error signal. The optical disk device further includes a measurement means which measures, before the lens center servo control, a first and a second amplitude values of the lens error signal. The measurement means calculates a current gain based on the first and second amplitude values, the latest gain which is currently set, and a predetermined target amplitude value. Then the measurement means sets the current gain to the generation means.

  • Patent number: 7755987
    Abstract: An optical pickup irradiates laser light upon a track of an optical disk and receives light reflected therefrom. A tracking actuator shifts an objective lens of this optical pickup in a tracking direction. A tracking error signal detection circuit outputs a tracking error signal based upon the reflected light received by the optical pickup. A phase compensation circuit generates a tracking drive signal based upon the tracking error signal, and outputs this tracking drive signal to the tracking actuator. A balance compensation value calculation circuit calculates a balance compensation value for the tracking error signal according to the tracking drive signal outputted by the phase compensation circuit. And a balance compensation circuit adds this balance compensation value to the tracking error signal detected by the tracking error signal detection circuit, and inputs this compensated value to the phase compensation circuit.

  • Publication number: 20080151707
    Abstract: An optical disk device includes an objective lens, a light detector, a lens holder, a focus drive actuator, a servo control section, and a control section. The focus drive actuator drives the lens holder along an optical axis of the objective lens. The servo control section and the control section control the focus drive actuator in such a manner that the objective lens is once separated from the optical disk and then brought close to the optical disk, and that when light reflected from the optical disk is detected by the light detector, the objective lens is brought close to the optical disk at a speed lower than a speed before the light is detected by the light detector. Further, the control section discriminates the kind of the optical disk.

  • Patent number: 7391692
    Abstract: A disk apparatus includes a light emitter that emits a light beam to be reflected on the optical disk, a light detector that detects a reflected light beam that is reflected from the optical disk, the light detector also outputting detection signals based on the amount of the reflected light beam detected, and a controller determines whether the optical disk is a recordable optical disk or not based on the detection signals. The controller also shifts a spot on the light detector at which the reflected light beam is incident by adjusting the focus point of the light beam on the optical disk in the radial direction when the controller determines that the optical disk is not a recordable optical disk. A wobble signal can be detected with high precision at low cost even when the position of the light detector is not balanced in the radial direction.
