Claims

[Scope of utility model registration request]

A semiconductor laser light source and an optical head unit having a built-in means for making the laser light from the light source incident on a recording medium and controlling focus and tracking of the laser light are rotatably supported by a pivot, and the optical head unit includes: A worm wheel is formed around the pivot shaft, a worm gear is meshed with the worm wheel, and the worm gear is rotated to rotate the optical head section around the pivot shaft, thereby moving the optical head section toward the recording medium. An optical head feeding device configured to move an optical head along a predetermined trajectory.
