Many of us are disappointed in the limited life spans of today’s media. Paper and film fade with time. Floppy disks, CD-ROM and DVD-ROM disks, flash drives, and other media also all have limited lifespans. Even microfilm is expected to last only about 300 years and that is only when stored in rigidly controlled temperatures and humidity and then ONLY if it is never used! (Microfilm scratches and wears quickly when used.)
Now a new storage media has been created that should last long enough for most of our needs: a million years or more. Even better, reading data from the disk can be read by the human eye when using a powerful magnifying glass or a microscope. I suspect those items will still be available in a few million years. The information is recorded at 1/30,000th of the original size and is preserved for all time. Water, acid, age, scratches or fire will not deteriorate the information.
