Abstract
An optical pickup comprises a light source section for emitting a light beam, a floating objective lens for focusing the light beam on an optical disk, a galvano-mirror capable of directing the light beam toward the objective lens and rockable for tracking control, a beam splitter for extracting return light from the optical disk, and a photodetector for detecting return light. The floating objective lens includes a lens for converging the light beam and a slider for holding the lens. The slider is lifted off the optical disk by means of air currents produced as the disk rotates. The galvano-mirror is located adjacent to the objective lens. In other words, the objective lens in a floating state is situated close to the galvano-mirror without intercepting the light beam incident upon the galvano-mirror.
