OPTICAL PICKUP

PROBLEM TO BE SOLVED: To provide a thin optical pickup having a floating objective lens. SOLUTION: This optical pickup is provided with a light source part 12 which emits light beams of parallel rays of light, the floating objective lens 16 which condenses the light beams, a galvano-mirror 14 which deflects the light beams toward the floating object lens, a beam splitter 20 which separates return light from an optical disk 30 and an optical detector 22 which detects the return light. The floating objective lens 16 is fixed on an ascendable slider 18 and is floated from the optical disk 30 by the air stream generated by the revolution of the optical disk 30. The galvano-mirror 14 is swingable because of the tracking control and is disposed adjacently to the floating objective lens 16. In other words, the floated floating objective lens 16 is brought close to the galvano-mirror 14 in so far as the floated floating objective lens does not shield the light beams which are made incident to the galvano-mirror 14.
