PROBLEM TO BE SOLVED: To provide an optical disk recording/reproducing device capable of preventing an objective lens from colliding with an optical disk even when servo drawing detection is failed during setting operation of focusing servo. SOLUTION: An optical disk recording/reproducing device 1 is provided with an objective lens 5 for converging a laser beam emitted from a laser beam source on the signal recording surface of an optical disk 100, a biaxial actuator 6 moving the objective lens 5 in the direction orthogonal to the signal recording surface of the optical disk 100 and driving and operating the objective lens 5 by a driving voltage and a control part 10 as a control means having the control function for avoiding the collision of the objective lens 5 with the optical disk 100 when the driving voltage exceeds a prescribed level stored in a storage part 9 at the time of setting operation of focusing servo. |
