Abstract: An optical pickup head includes a first light source, a second light source, a base, a light adjusting unit, and a light guiding unit. The first light source emits a first wavelength light beam to read a first data density optical storage medium. The second light source emits a second wavelength light beam to read a second data density optical storage medium. The base includes at least a slant surface for reflecting the first wavelength light beam and the second wavelength light beam, so that the first wavelength light beam and the second wavelength light beam are parallel with each other. The light adjusting unit adjusts the first wavelength light beam and the second wavelength light beam to the same optical axis. The light guiding unit guides the first wavelength light beam and the second wavelength light beam to the first data density optical storage medium or the second data density optical storage medium.

Abstract: An optical system (20) for efficiently collimating an elliptical light beam includes a light source (21), a collimator (22), and at least one prism (23,24). The light source is adapted for providing an elliptical light beam defining different diverging angles in different directions, wherein any cross-section of the elliptical light beam emitted from the light source defines a long axis and a short axis which are perpendicular to each other. The at least one prism is used for reconfiguring the elliptical light beam, thus obtaining a parallel round light beam having equivalent short axis and long axis.
