Abstract

Systems and methods, e.g., optical apparatuses, for digital optical information storage systems that improve the speed, signal to noise, controllability, and data storage density for fluorescent and reflective multilayer optical data storage media. The systems and methods include an optical system for a reading beam of a data channel from a moving single or multi-layer or otherwise 3-dimensional optical information storage medium that comprises at least one optical element characterized by restricting the field of view (FOV) of the reading beam on an associated image plane to 0.3 to 2 Airy disk diameters in a first direction.

Abstract

An optical information storage medium includes a substrate and a multilayer polymeric film. The multilayer polymeric film has a first surface and an opposite second surface that extend the length of the multilayer polymeric film. The second surface is adhered to a surface of the substrate. The multilayer polymeric film includes a plurality of coextruded alternating polymeric active data storage layers and polymeric buffer layers.
