Abstract
An optical information storage medium includes a multilayer film that includes a plurality of extruded alternating active data storage layers and buffer layers, which separate the active data storage layers. The active data storage layers and buffer layers have thicknesses that allow the active data storage layers to be writable by permanent or reversible one- or multiphoton, linear, nonlinear, or threshold optical writing processes to define data voxels within the active data storage layers that are readable by an optical reading device.
