Multiple beam optical memory system with solid-state lasers

摘要

An optical memory system employing multiple reading/writing optical beams from solid state lasers for simultaneously reading from a writing to multiple tracks of optical media to allow reading/writing of closely spaced adjacent tracks, a number a feature are disclosed. These include using vertical writing surface emitting lasers forming an array of beam sources, using lenslets associated with array, modulating the beams, and providing various optical elements and combinations of optical elements to compensate for beam and system imperfections.
