http://www.americanmicrographics.net/aboutmic.htmThe Role of Microfilm in the Digital World
Why Microfilm?
Information is the basis of our society. Whether this information starts out on paper or as digital data, it’s ultimately too fragile to store long term in those forms.
Software upgrades and hardware changes cause new technologies to obsolete themselves, often in only a matter of years. Think about it. What if you back up information onto magnetic tape or floppy disks. Are you confident that it will still be readable 25 years from now? What if it was saved in a software format that no longer exists? How will you open that file?
For mission-critical information, the kind that needs to be kept for legal or archival purposes, there is a low-cost and extremely effective storage alternative. You’ve probably used it yourself. It’s called microfilm.
What is Microfilm?
Microfilm is a unique backup medium because it can be read by the eye, without the need for hardware or software. Like paper, microfilm is an "analog" medium that can be viewed by anyone, anywhere. It’s different from digital data, such as information stored in a computer, which is completely dependent on technology.
Microfilm is also much less costly for backup than digital media, for two reasons: first, microfilm technology is consistent – it doesn’t require continual hardware/software upgrades. Second, unlike digital graphic devices, it’s not limited by "dots per inch", since a single photograph holds virtually an infinite amount of detail.
Another microfilm benefit is that it’s always acceptable as courtroom evidence because the information cannot be altered. This is not true for digitally stored information. And, unlike typical digital media, microfilm has never "crashed".
