ABSTRACT:
An optical memory system employing multiple reading/writing optical beams for simultaneously reading from or writing to multiple tracks of optical media to allow reading/writing of closely spaced adjacent tracks. 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.
