We discuss an extension of our previous research that uses image-plane optical masks to achieve superresolution in confocal scanning microscopy to the coherent optics of digital versatile disc readers. The theory and the design of superresolving optics for such high-numerical-aperture scanning coherent imaging systems is presented. A superresolving optical reader would permit superdense optical data storage, giving an improvement over the equivalent conventional storage densities by at least a factor of 2.
