PROBLEM TO BE SOLVED: To provide an optical disc device capable of improving the stability of servo loop gain adjustment.SOLUTION: An optical disc device 100 includes an optical pickup 3 and voice outputting means (70) for outputting a voice. The optical disc device 100 includes: servo means U1 for performing a control for making the light (80) coming from the optical pickup 3 trace a reference position; and adjusting means U2 for adjusting the gains of control loops LP1 and LP2 of the servo means U1. The adjusting means U2 includes voice output suppressing means U3 for suppressing the accident that, when the gains are adjusted, a voice making the adjustment of the gains incorrect is output from the voice outputting means (70).SELECTED DRAWING: Figure 1 |
