Abstract:
1. An optical disk device comprising: a laser diode; a movable mirror operable to deflect a laser beam emitted directly from the laser diode, the movable mirror disposed in such a position that the laser beam is incident on the movable mirror as divergent light along an unimpeded light pathway without being converted to parallel light; a package housing the laser diode and the movable mirror; an optical head section disposed outside the package, and adapted to focus the laser beam deflected by the movable mirror on an optical recording medium; and a drive control section operable to shift the optical head section in a radial direction of the optical recording medium and to drive 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 and is disposed adjacent to the laser diode, wherein the laser beam deflected by the movable mirror goes outside the package without optical modification.
