Abstract
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.
Claims5
An optical disk device comprising:
- a laser light source;
- a movable mirror for deflecting a laser beam emitted from the laser light source;
- an optical head section which focuses the laser beam deflected by the movable mirror on an optical recording medium;
- and
- a drive control section which shifts the optical head section in a radial direction of the optical recording medium and drives the movable mirror based on the laser beam reflected from the optical recording medium to carry out tracking control,
- wherein the movable mirror is incorporated in a micro electrical mechanical system, the micro electrical mechanical system incorporating the movable mirror is housed in a package accommodating the laser light source, and
- the movable mirror is driven by electrostatic force at a frequency of 0.5 KHz or higher.
