This might be a bit too fictional but here's the scenario. Task is to store small amount of data (Less than 1Mb) for centuries to come.
Environment specs and possible hazards follows:
- Usually at room temperature, but possible heat/cold spikes. Meaning average is 22°C, with -20°C and 45°C extremes.
- Electromagnetic waves, slight magnetic force, dense radio signals, are included but not too strong.
- Humidity level of the container is 70%
- The storage solution won't be exposed to any brute force
- Atmosphere of the environment is dusty.
- Standard air pressure
The storage solution is expected to be available after 100 years of dormant rest(will not be connected to an electric circuit, will not be read). In these circumstances, what is the best storage device to ensure data that is stored will be safe and ready to be read after 100 years ?
For the sake of experiment, assume that the budget is unlimited or trivial.
Harddisks, SSD's, floppy disks, optical drives and many other are available and can be considered. My bet is harddisk, since logical gates or latches in SSD might be released after a long period of time with no electricity. Meaning the data will be lost or partially corrupted.
Every idea counts, thank you.
PS. Not certain if this is the right stack site for this question. Couldn't find a one that qualifies better.
