Abstract

With recent advances occurring in media development and control system designs, little attention has been given to optical subsystem design, a more mature, reliable technology. However, the unique performance goals of a read/write optical disk system offer interesting problems and opportunities to a lens designer. An optical system recently designed with RCA, reshapes the nonsymmetrically emitted beams from a ten-element laser diode array, and images them onto a data storage disk (Fig. 1). The final component is a, lightweight infinity-corrected microobjective, controlled by a two-axis servo system to maintain radial tracking and focus.
