ABSTRACT:
An optical pickup includes a light emitting device, a prism, and an objective lens. The light emitting device emits a laser beam. The prism has an entrance face and an exit face. In the prism, the laser beam emitted from the light emitting device is perpendicularly incident on the entrance face, is parallel-shifted, is perpendicularly reflected, and is emerged from the exit face. The objective lens focuses the laser beam emerged from the prism on a recording surface of an optical disk.
