Table 1-Record Media
Record media/form | Media expected life | Comments and standards |
1. Paper and card stock (hardcopy). | Archival permanency | For each document, paper stock should be selected with a life expectancy equal to or greater than the retention period specified for that document. |
2. Magnetic Storage: | ||
a. Computer Disk (i.e., hard disk and floppy disk). | five years. | Assumes storage in a controlled environment with a temperature and humidity range of 60° - 80°F. and 40- 60%, respectively. Assumes regular system of copying and re-generation is utilized. |
b. Tape (e.g., computer tape and videotape). | five years. | Same as above. |
c. Punched tape or card. | Archival permanency. | For each record, tape media (paper, mylar, metallic base) should be selected with a life expectancy equal to or greater than the retention period specified for that record. |
3. Microforms: a. Microfilm, including Computer Output Microfilm (COM), microfiche, jackets, and aperture cards. | Archival permanency. | Assumes processing to standards and storage in a controlled environment with a temperature and humidity range of 60° - 80°F and 40 - 50% respectively. (Ref American National Standards Institute (ANSI) standards PH 5.4 - 1970, PH 1.41 - 1970, PH 1.41-1976, PH 1.26-1979, PH 1.43 - 1961, or most current standards as accepted by the National Archives for use by Federal agencies. See 41 CFR 101 - 11.5) |
b. Updatable type. | Dependent on use of media. | For temporary records not requiring archival permanency so long as the microform or film selected has a life expectancy equal to, or greater than, the retention period for that record. Same storage condition as for microfilm. |
c. Metallic recording data strips. | Archival permanency. | Same storage conditions as for microfilm. |
4. Optical Disk (including CD-ROM, WORM, and erasable types). | ten-20 years. | Assumes regular system of copying and regeneration is available and utilized. Reference the following quality controlsing quality controls: (1) disk technology does not allow deletion or modification of record images, (2) image of each record is written onto two optical disks, (3) the legibility of each record image is verified to ensure that image is legible on both disks; if image is illegible, the hard copy record is maintained as record copy, (4) one disk is stored in document imaging system for on-line retrieval, (5) second (backup) disk is stored in records storage facility meeting requirements of ANSI N45.2.9- 1974 for single copy storage in separate remote location, (6) records stored on disk are acceptably copied (including verification) onto new disk before manufacturer's certified useful life of original disk is exceeded, (7) random inspections of images stored on disks are performed to verify non-degradation of image quality, and (8) if replacing imaging system with incompatible system, records stored on old system's disks must be acceptably converted (including verification) into new system before old system is taken out of service. |
