摘要： A manipulator includes a main unit movable to a specified target position, an arm unit rotatably provided on the main unit, and a posture controller. The posture controller controls the posture of the arm unit so that a front surface of the arm unit facing forward in a moving direction of the main unit is not orthogonal to the moving direction of the main unit when the movement of the main unit is performed. The arm unit may be inclined obliquely backward with respect to a moving direction of the main unit when the main unit is moved to a specified target position.

摘要： An optical head is driven in a tracking direction with respect to a rotating optical disc. The optical head includes a light source, an optical block, a condenser shifter, and a rotating mechanism. The light source is used to read and write data from/on the optical disc. The optical block supports the light source. The condenser shifter includes a condenser, a movable body, a base, a focus direction drive mechanism and a tracking direction drive mechanism. The condenser focuses light, emitted from the light source, toward the optical disc. The movable body supports the condenser. The base supports the movable body elastically such that the movable body is able to shift in a focus direction and in the tracking direction. The focus and tracking direction drive mechanisms are provided to shift the movable body in the focus and tracking directions, respectively. The rotating mechanism rotates the condenser shifter around a predetermined axis with respect to the optical block on at least one of a first plane, which is parallel to the tracking direction and perpendicular to the optical disc, and a second plane, which is perpendicular to the tracking direction.

摘要： An information recording/reproducing apparatus includes a focusing optical system for focusing light from a light source on an information recording medium as a light spot and an error signal generation system for generating an error signal that represents the positional deviation between an information track and the light spot on the information recording medium from the light reflected by the information recording medium. The apparatus further includes a tilt measurement system for measuring the amount of relative inclination between the focusing optical system and the information recording medium and an offset application system for performing off-track of the light spot by applying an electric offset corresponding to the measured amount of inclination to the error signal. Since the electric offset that corresponds to the amount of inclination is added directly to the error signal, the apparatus does not require a complicated algorithm and can improve the recording and reproduction characteristics easily at low cost.
