Abstract
Apparatuses, products, devices and methods of manufacture consistent with the invention include optically readable media with at least one mechanism, chemical, agent, and/or process for limiting the time period that at least a portion of encoded information can be read and/or accessed by an optical beam and/or reader capable of reading the encoded information.
Claims54
An optical medium readable by at least one pre-selected optical beam comprising:
- a first substrate;
- a first data storage layer proximate to said first substrate, wherein said first data storage layer comprises an encoded information receiving layer and a reflective layer;
- a second data storage layer, wherein said second data storage layer comprises an encoded information receiving layer and a reflective layer;
- and
- at least one intervening layer between said first data storage layer and said second data storage layer;
- wherein said at least one intervening layer comprises a read inhibiting agent, said read inhibiting agent in communication with at least one of said first data storage layer and second data storage layer, wherein said read inhibiting agent permits access to at least a portion of said at least one of said first data storage layer and second data storage layer for a predefined period of time and after such predefined period of time said read inhibiting agent irreversibly prohibits access to said at least a portion of said at least one of said first data storage layer and second data storage layer;
- wherein said first data storage layer and said second data storage layer are readable with different optical wavelengths.
