    摘要： An optical disk apparatus includes a light emitting unit, a light detecting unit, a tracking error signal generating unit, and a tracking control unit. The light emitting unit emits a single light beam onto an optical disk. The light detecting unit includes at least three light detecting portions, each being configured to receive light reflected off the optical disk and produce corresponding output. The at least three light detecting portions are arranged in a track direction of the optical disk. The tracking error signal generating unit generates at least two types of the tracking error signal using the outputs from the at least three light detecting portions. The tracking control unit performs tracking control on the optical disk on the basis of the tracking error signal.

    摘要： A focus controller for focusing a light beam and positioning the focused light beam onto a signal recording layer of a signal recording media is disclosed. The controller comprises a light beam focusing means having a numerical aperture of 0.6 or more; a focus controlling means for positioning the light beam focused by the light beam focusing means onto the signal recording layer of the recording media; and an offset adjusting means for adjusting an offset between the focused light beam positioned by the focus controlling means and the signal recording layer of the recording media. The controller positions the light beam focused by an objective lens onto the signal recording layer of a recording media; moves the objective lens within a predetermined optical-axial range, detects an amplitude of a signal read from the recording media at either end of the optical-axial range, and adjusts an offset between the focused light beam positioned by the objective lens and the signal recording layer, depending on a difference between the amplitudes of the detected reproduced signal.
