Objective lens design for multiple-layer optical data storage

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The methods of compensating aberrations in multiple-layer storage with common objective lens designs are discussed. A new class of objective lenses that could be useful for this technology is also introduced. Mechanical change in the compensation optics to focus at different depths are not entirely satisfactory either due to a restricted range of compensated thickness or due to extremely tight alignment tolerances. Common objective-lens shapes do not perform well off axis due to a large amount of coma. Instead, changing the shape so that the radii are symmetric and nearly equal to the surface separation produces excellent results.
