Abstract:
An optical pickup apparatus comprising:a supporting frame a laser light emitting device, supported by the supporting frame which emits light having an elliptical far field pattern having a short axis and a long axis; a deflector, operable to deflect laser light emitted from the laser emitting device, the deflector supported by the supporting frame; an objective lens, supported by the supporting frame, operable to converse the laser light deflected by the deflector onto an optical recording disk; wherein the deflector is adjustable to adjust the deflection angle of the deflected laser light, such that the short axis of the reflected light is aligned with a radial direction of the optical recording disk; and wherein the deflector is adjustable to adjust the distance between the deflector and the laser light emitting device, such that the center of the intensity distribution of the reflected laser light is aligned with the optical axis of the objective lens; and a lens driver, supported by the supporting frame, the lens driver operable to move the objective lens in a focusing direction and a tracking direction of the optical recording disk.
