Before computer technology became widely introduced into offices, one of the most popular data storage solutions was through the use of microfilms and microfiches. Both data storage mediums are designed to be inexpensive long term archival formats. Unfortunately they are slow and inefficient means of data storage compared to today's computer based systems.
As this article shows, it's now easy to scan and convert archived data stored on aperture cards, microfilm and microniche. Data can be converted to a range of digital file formats, then used in other data processes such as document tracking and management. Microfiche scanning can either be carried out in house using specialised hardware, or it can be outsourced to one of the many scanning service companies.
