Microfilm Is Not Dead

If certain types of devices are in circulation for a long time, some consumers believe they are no long usable. However, the inexpensive analog technology of microfilm is still in use and holding on alongside innovative data storage solutions. This analog storage system is definitely alive and serving its purpose. It is still an excellent solution for archiving public records.

Furthermore, scanning is easy and data remains in a durable and accessible format while utilizing only a small amount of storage space. Evolving initially during the 1800’s, the system began its popularity during the 1920’s. A banker by the name of George McCarthy created it for making permanent film copies of bank records. It functions similar to that of a large microscope. Overall, two types are still in use.

Document imaging services use vesicular film or silver halide forms of film. Vesicular film is inexpensive and uses tiny microscopic bubbles to make and image on the polyester strip. The Silver type transfers images to film using the traditional procedure of silver emulsion on a polyester strip.

A close kin to microfilm is microfiche. It is a card of photograph film with tiny letters too small to read with the naked eye. The machine lens expands the images and makes the contents easier to read. Document imaging services can now change then save data in template format. Film densities automatically adjust as the conversion process takes place. Libraries and government offices worldwide use these photographed films for mass data storage.

Analog storage media is the most compact in that thousands of books, periodicals and newspapers only require a storage space of about 16 inches. Easily, each card has the ability to hold up to 130 pages of data. Added space also contributes to cutting operating costs. Fortunately, this storage method uses less paper and therefore plays an important role in conserving natural resources.

Document imaging services now take digital images and content and transfer them to mass data storage areas for up to 500 years. Furthermore, document imaging service experts can extract data effortlessly from microfiche documents and transform them into DVD, CD or electronic formats.
