摘要： PROBLEM TO BE SOLVED: To provide an optical disk drive in which an image can be recorded by a laser beam on an image recording layer provided on a label face side. SOLUTION: A first objective lens L1, defined as a lens arranged on an inner peripheral side, is so constituted as to perform read operation of data for image recording control provided on an inner peripheral side of the optical disk by the first laser beam irradiated from the first objective lens L1 and to record an image signal on an image recording layer disposed on the optical disk by a second laser beam irradiated from a second objective lens L2. The radial direction distance between the first objective lens L1 and the second objective lens L2 is measured and thereby the calibration operation of the image signal recording position is performed.

By folding a light-receiving optical path of the reflected light from the target area by the folding mirror 51, the emission unit 3 and a light-receiving unit 4 can be arranged efficiently in space below the mirror actuator 2. Thereby, the miniaturization of the laser radar 1 can be achieved.
