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.
Microfilms cannot typically be ascertained by the naked eye, and they must first be magnified. There are a few machines designed just for this purpose. The most common of the machines have a magnifier and a simple projector.
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.
While the machines are expensive, they are not complicated to use and does not require specialized software or skill to use them. Digital storage media can only be read on things like computers. Some institutions do use microfiches and digital storage media interchangeably. The polyester material which the images are printed on is quite stable, and in temperature controlled environments, the films can last as long as 500 years.
Opposed to compact discs, which only have an estimated life span of 75-100 years, the films are a much safer bet when it comes to storing data for endurance. Compact discs can last longer depending on the materials they are made of and how they are handled and stored. Computer based storage media is typically more delicate than films. Microfiches are typically easier and cheaper to replace when films are damaged.
Microfiches do have some disadvantages, but its advantages outweigh the disadvantages. While the need of special equipment is required, it is still bulky and unideal for everyday transportation. The films and the machines to view them are not modern day trends and are considered specialized items.
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 the films are near impossible to view accurately without a microfiche scanner handy, the machines can be integrated with digital devices such as computers and data formats. Without a microfiche scanner, one has to travel to a location that has one for easy viewing, access, and control. With the right scanner, digital interchange is straightforward to use.
