Microfiche Scanner Inner Workings And What To Expect

By Grace Rivas

When a microfiche scanner is used, a thin transparent film is used to store information in a miniature system. The most common method of reading the cards is to use a reader machine that magnifies the film data. Libraries and museums use these machines often as a way to store resources efficiently. While most organizations may employ digital means to store data, microfiches are used widely and some may argue that they have a longer life span.

In case it got by you, microfilms are much more durable and stronger than digital data mediums. A small film is around 155mm x 148mm. In inches, it translates to 4 in x 5.8 in. Typically, microfilms used to embed documents and images are made from a polyester base.

Microfiches are difficult, if not, impossible to view with the naked eye. You must place the films in a scanner that will magnify and project your document for your viewing ease. The machines are basically simple scanners and projectors.

The machines are costly. They are also unique and are employed in institutions that find documentation critical to their operations. Various optical scanners can be used to convert the films data into digital format that can be interchanged between computers. When storing a large amount of microfilm, a small storage cabinet is sufficient. A small storage cabinet of microfiches can hold up to 10,000 pages of context.

You can find a good quality machine, and they are easy to operate. You do not need a computer or digital storage device. The machines have a standalone purpose for a standalone medium. The films are durable, stable, and can last up to 500 years when stored in a temperature controlled room.

In comparison, CDs have a relatively short life span, and they are not ideal solutions for long-term storage. CDs typically do not last beyond 100 years, unless concentrated care is exercised. Computers and digital storage mediums have a short-term life span in contrast to microfilms and scanners. Microfiches last a lot longer and are easy to replace when films are damaged or lost.

Microfilms have little disadvantages. The main disadvantage is that you need viewer machines to view the documents on the film. The machines are bulky, and they are not suitable for on-the-move circumstances. Finding a good machine can be difficult and these machines are unique and rare.

The main theme for microforms is contract on black and white images. Using microforms to store high quality images is not ideal, and photographs do not look as good as modern digital devices portray them to be. When color ink is used in microform, it can degrade with exposure to sunlight or bright light.

While it is possible to share files from a microfiche scanner via digital formats, it can be difficult. If one has the right equipment, it is a relatively straightforward process to set up. If a document is only available via microform, one has to travel to the physical location where a reader is to view the documents.
