Systems, materials, and methods for increasing the storage capacity of
optical recording media are provided. In one aspect, the systems of the
present invention take advantage of high NA optics to realize ultra high
storage capacity. In another aspect, the systems of the present invention
include the use of a liquid interface between the recording medium and a
liquid interface singlet objective lens to increase storage capacity. The
invention also provides for a material system that allows shorter
wavelengths to be used for recording and readout. Further, the invention
provides for recording methods wherein the wavelength for recording to a
medium is longer than the wavelength for reading from the medium.
Additionally, the invention includes a multilayer structure for recording
media that increases storage capacity. In another aspect of the present
invention, high NA optics and related systems and methods are utilized to
increase the storage capacity of optical storage systems.
