Systems and methods of determining optical data storage lifespan

A method of determining a health state of an optical storage medium, the method comprising:

• directing, from at least one emitter, focused light to a location within a header region of the optical storage medium, wherein the location includes different physical states of the optical storage medium corresponding to stored data including lifespan data encoded within the header region of the optical storage medium;
• detecting reflected light from the optical storage medium with a reader, wherein the reflected light is the focused light reflected from the location;
• processing the reflected light into read data;
• determining an expected lifespan based on a life expectancy of the optical storage medium, wherein the life expectancy is based on the lifespan data encoded within the header region of the optical storage medium;
• determining a decay state of the stored data based on readability of the read data;
• correlating the life expectancy and the decay state of the stored data to provide a correlation;
• and
• providing the health state of the optical storage medium based on the correlation.

An optical data system, comprising:

• an optical storage medium, wherein the optical storage medium comprises:
• a header region encoded with lifespan data;
• a read subsystem comprising:
• a base, wherein the base is configured to support the optical storage medium;
• a laser system comprising:
• one or more lasers configured to focus light on one or more surfaces of the optical storage medium;
• one or more detectors configured to read the lifespan data or stored data of one or more surfaces of the optical storage medium based on the focused light;
• a control system comprising one or more processors;
• and
• memory storing instructions executable by the control system to cause the control system to:
• control the laser system to read the lifespan data within the header region of the optical storage medium;
• determine an expected lifespan based on a life expectancy of the optical storage medium, wherein the life expectancy is based on a writing date of the optical storage medium;
• control the laser system to detect a decay state of the stored data, wherein the decay state is based on a readability of the stored data, and wherein the readability of the stored data is analyzed by the laser system based on an efficacy of the one or more detectors to read the stored data of the one or more surfaces of the optical storage medium;
• correlate the life expectancy and the decay state of the stored data;
• and
• provide a health state of the optical storage medium based on the correlation.
