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.
Claims5
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;
- and
- a read inhibiting agent, said read inhibiting agent in communication with said first data storage layer, wherein said read inhibiting agent allows access to at least a portion of said first 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 first data storage layer;
- wherein said optical medium is disc shaped having an inner diameter and an outer diameter;
- wherein said first read inhibiting agent is localized to at least one of (i) the inner diameter and (ii) to a wedge shape, wherein the wedge shape is widest at the outer diameter and narrowest towards the inner diameter.

- 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;
- and
- a read inhibiting agent, said read inhibiting agent in communication with said first data storage layer, wherein said read inhibiting agent allows access to at least a portion of said first 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 first data storage layer;
- wherein said first data storage layer comprises instructions that direct where said at least one pre-selected optical beam is located in relation to said first data storage layer, the order the regions in the first data storage layer are accessed, and the length of time the pre-selected optical beam remains located in a particular region of the first data storage layer.
