There are good reasons to convert to digital documentation. The continued promotion of digital switching technology with the ease of combining and many options for dealing with digital documents digital form should make the most preferred choice for storage of documents. Nevertheless, it returns also an interesting trend to convert digital images to microfilm.
Traditional forms of storage of documents, including microfilm, aperture cards and paper. These formats are typically converted to TIFF images or PDF files if digitized. A summary of the traditional format are as follows:
Paper: This includes large-scale drawings, books, manuals, etc. It can be stored in files, drawers, shelves, chests, cabinets and
Microfiche: A flat film, which contains a matrix of micro-images can be stored in boxes, file cabinets, drawers and envelopes
Microfilm: A roll or be perforated roll of film that can be in 35-mm or 16 mm> Micro-image format contains. Filed in open reel or cassette type systems.
Aperture cards: A mounted punch card with a microfilm chip. Can be stored in boxes, file cabinets, drawers and envelopes.
Why convert to digital format again on microfilm?
Many of our customers have requested this, and the reasons seem practical, but they are really valid. One gets the impression that microfilm lasts longer and is safer than in the digital storage is required over severalDecades. Many organizations, when faced with the need for storing more than 30 to 50 years, decide to microfilm, but is there really any basis for trusting not digital. Many institutions such as libraries and government agencies simply want "eye readable" documentation, the other words that are not digital.
How long will last for microfilm?
Can be stored after a few sources, high-quality microfilm under good conditions well over 100 years. In addition, microfilm andMicrofilm scanners and storage for a very long time (more than 100 years), the technology and system since it was shown that the long-term archiving work.
What about digital technology?
The answer depends, as there are many methods for digital storage. The most common are hard disks, CD, DVD, Optical DVD, flash drive, and magnetic tapes. Even within each format there are many levels of quality and durability, depending on material and workmanship. Forthis article we will assume high-quality products designed for archiving purposes.
Magnetic tape is practically given in the last 30 to 40 years (even longer). High-quality read / write CD can take a long time, maybe even 100 years. Flash drives can theoretically be used for a long time without moving parts, but at last, by their nature, you would not have much confidence in reliable data storage. DVDs can be as long as CDs. To be done due to the relative novelty of digital technology, we do not have muchStorage demonstrate experience, reliability, over a 50-year period.
From a document storage point of view the answer is not as simple as the media lasts longer. The medium must be stored and treated for 100 years yet. The conditions that these media can make a big difference to be maintained. Although it seems that both microfilm and digital storage in a position to take a very long time could be the storage and management systems and facilities are the weakest link. It seems muchmore likely that both media would be damaged or lost over a period of 50 years by careless handling or storage.
There are obviously many more variables with digital storage. Digital technology changes very quickly, and systems are often the migration of data from a backup system, on the other hand need to keep data from becoming stored in outdated formats. This would require active storage management over a very long period.
The technology of microfilm on the other sideHand is very stable and very little has changed since its inception. Scanning of microfilm, or reading is very simple and the technology should always be around. You do not have to be about formats or technological changes, with microfilm, where digital technology still seems to be developed to mind. Thus microfilm is a more reliable storage system for extremely long periods of time? In our opinion, yes, but we still have much faith in digital technology. The ultimate risk is probably more linkedthe storage and management organization and system and not the technology.
