摘要： An optical disc drive includes an optical head having a stationary portion and a movable portion. The movable portion supports an objective lens for converging a beam emitted from the stationary portion on an optical disc. The movable portion moves radially across an optical disc in order to irradiate the beam on a desired track of the optical disc. The optical disc drive is further provided with an aberration correcting lens that corrects aberration caused by the objective lens. The aberration correcting lens is mounted on the movable portion so as to be movable in a direction substantially orthogonal to a movable direction of the movable portion, which may parallel or perpendicular to the optical disc. The aberration correcting lens is moved in accordance with a variation of the aberration caused by the objective lens.

摘要： Disclosed is an optical disc drive for reading/writing data from/on an optical disc. The disc drive is provided with a laser source, an objective lens system, a deflection mirror between the laser source and the objective lens system. An incident angle of the laser beam incident on the objective lens system is changed by rotating the deflection mirror. Further, a relay lens system is provided between the deflection mirror and the objective lens system. A diffraction grating is provided between the laser source and the deflection mirror. The diffraction grating divides an incident beam into at least 0th order beam and ±1st order diffraction beams having predetermined diffraction angles.

摘要： A head unit control device comprising an optical head unit for radiating a laser beam onto a magneto-optical disc, a magnetic head unit including a floating magnetic head and a fixed magnetic head. Luminous flux is radiated onto the magnetic head unit and the optical head unit. The luminous flux reflected by these units is sensed by photo detectors, so that a relative position error signal is generated by a sensing circuit. When information is overwritten onto the magneto-optical disc on which information has been already recorded, the floating magnetic head is moved in synchronization with the optical head, based on the relative position error signal. When information is recorded on the magneto-optical disc on which information has not been recorded, the fixed magnetic head is moved in synchronization with the optical head, based on the relative position error signal.

摘要： In a reflecting plate provided on an optical head arranged to be movable at least in a predetermined direction within a device such as a compact-disk player and the like, a multiplicity of irregularities are formed on a surface of the reflecting plate for causing diffused reflection of light. Then, since the light is diffusely reflected at the edge portions of the reflecting plate in the predetermined direction, an area, in which a linear relation exists between movement of the optical head and the output level of an amplifier signal in accordance with the movement can be wider as compared with the case in which these irregularities are not formed.
