Various optical elements and other means are incorporated to enable the beams as a group to remain focused and properly tracking as the beams as a group scan across the tracks. Means are also provided for modulating the beams to reduce crosstalk. Various optical elements and combinations of optical elements are provided to compensate for beam and system imperfections.
