Abstract
An optical memory device and a method for manufacturing thereof. An optical memory device has at least one data layer formed on a substrate. An upper surface of the substrate is formed with a pattern comprising a plurality of regions which are capable of obtaining, when covered by a recording medium, desired optical properties different from those of the substrate. The patterned surface of the substrate is coated with the recording medium. The recording medium is removed from the patterned surface after the recording regions have obtained the desired optical properties.
Claims6
A multi-layered optical memory device comprising a plurality of spaced-apart data layers containing a material excitable by incident light to produce fluorescence, each layer having a patterned surface thereof, the pattern being in the form of a plurality of regions containing the fluorescent material and spaced by regions of the layer transparent with respect to the incident light and to said fluorescence, thereby enabling access of all data layers by the incident light.
