In the "Safety First" strategy of the "three major strategies" during the "12th Five-Year Plan" period, the National Archives Bureau clearly stated that the focus is on improving the security capacity building and improving the security of the archives. A confidential file security system. Perform offsite backups of important files. For all sets of files or copies of files, be sure to store at least one set in a different location. For important electronic files, not only should they be homogeneously backed up, but also heterogeneous backups should be converted into microfilm or paper files in time to ensure they are readable for a long time.
In the era of high development of digital technology, microfilm technology and digital technology are closely combined—the digital-to-analog image integration system, giving full play to the characteristics that microfilm technology is longer than “storage†and digital technology is longer than “useâ€. In other words, by using the Kodak digital archiver and the corresponding software system, the advantages of digital technology, namely the speed, logic and convenience of digital transmission, and the security, reliability, permanence and reality of microfilm technology. Sexuality and economics, as well as legal validity, are combined to incorporate the technical track of modernization of information and materials.
The best medium for off-site, heterogeneous storage archiving - microfilm
The miniature technology is mature and stable, and there are perfect standard specifications.
In the long-term development process, microfilm technology has formed a set of standards from production work to storage specifications. At present, there are more than 30 ISO standards, and China's GB standards are also fully improved. Microfilms of various specifications are only in accordance with ISO and GB standards. It can be used in any country. In 2009, ISO11506 "File Management Application - Electronic Data Archiving - Computer Output Microfilm (COM) / Computer Output CD (GOLD)" standard was issued. At the same time, the National Archives Bureau issued DA/T44-2009 "digital file information output to microfilm. Technical specifications on film
The biggest advantage of microfilm is its long shelf life.
According to the test data released by the KODAK company's technical report in early 1997, the shelf life of microfilm is 1000 years. When the Great Hanshin Earthquake occurred in Japan in 1996, most of the information stored in magnetic media and optical discs was lost, and the information stored on the microfilm was intact. At the 2008 Wenchuan Earthquake in Sichuan, microfilms played a key role in quickly restoring production.
Microfilm has legal credentials
The microforms have the same legal status as the originals. Article 21 of Chapter 4 of the "Measures for the Implementation of the Archives of the People's Republic of China" promulgated by the State Council on October 24, 1990 establishes that the microfilm has the same legal status as the original file. This provides an effective legal basis for the use of microforms instead of the original files and the destruction of archives or remote storage.
Microfilm is safe and reliable and irreplaceable
According to relevant information reports, there are more than 850 large financial institutions in the world, which need to store more than 10 years of data in the computer for security reasons, all of which are stored on the microfilm through the COM system. It can be seen that the role of microfilm as a safe storage of documents has not been replaced.
Microfilm records optical images. Reading this image has little dependence on the device. In the most difficult time, a magnifying glass with a higher magnification can be easily read.
As a file medium, microfilm has not replaced the microfilm for long-term preservation of files in the long-term safe storage of archive information. Microfilm can be stored permanently and is immune to viruses, technological advances, equipment upgrades and other abrupt factors. Nowadays, not only the information of the paper carrier needs to be preserved through microfilm technology for long-term preservation. For the sake of safety, digital documents and data materials with certain historical value and academic value can also be directly converted into microfilm by digital archiving machine for safe preservation.
