Abstract
Apparatus for scanning a rotating optical disk, including: a scanning assembly for directing a light beam toward the disk surface and causing the beam to traverse the surface; a focusing lens unit disposed in the path of the beam to focus the beam at the surface; and a light beam deflecting element disposed in the beam path between the scanning assembly and the focusing lens unit to deflect the beam toward a direction perpendicular to the surface. The focusing lens unit may be composed of a group of individual focusing lenses spaced apart parallel to the surface, each having an optical axis that is perpendicular to the surface and each being associated with a respective track; and light directing elements disposed in line with the path at a location for directing light substantially entirely to a respective one of the individual lenses.
