| 摘要 |
An optical disk device in which the laser beam emitted from a laser light source and deflected by a movable mirror is focused on an optical recording medium by an optical head section. Tracking control is carried out by a drive control section based on the laser beam reflected from the optical recording medium. A micro electrical mechanical system incorporating the movable mirror is housed in a package accommodating the laser light source. The movable mirror is driven by electrostatic force at a frequency of 0.5 KHz or higher.
