Preservation strategy.
For an electronic image system containing public records with a retention period of ten years or longer or records containing archival information, one or more of the following preservation strategies must be employed:
(1) Retain the original paper documents;
(2) Microfilm the original documents;
(3) Migrate optical media and magnetic media at least every ten years or sooner as is necessary to avoid technical obsolescence, loss of readability, and excessive read error rates; or
(4) Record the electronic images on industry standard microfilm at the same density at which they were scanned.
