| 20150121404 | OPTICAL DISC DEVICE AND FOCUS CONTROL METHOD THEREOF - The present invention aims for shortening a time required before the focus control is started. The initial focus position is detected, while the optical disc is not rotated, by making the objective lens approach to the optical disc from the first separation position farther from the optical disc than the focus position. The focus control is performed so that the objective lens tracks the focus position of the data recording layer, while the optical disc is rotated, by making the objective lens approach to the optical disc after the objective lens is returned to the second separation position farther from the optical disc than the first separation position. The initial focus position can be focus position of the data recording layer. The second separation position can be a position farther from the optical disc by a predetermined distance than the initial focus position. | 04-30-2015 |

Accordingly, the user can find out that the storage medium is not mounted before the digital camera has been brought outside for use. Thus, it may be possible to prevent a failure in which the user first realizes that they forgot to mount the storage medium only when they are already away from home. | 05-14-2009 |
