340 - Physical Medium (R)

Physical substance (e.g., acetate, canvas, clay, film, glass, vellum, or wood) and configuration (e.g., cartridge, chip, dot, fiche, globe, sheet, and audio-, magnetic-, micro-, ultra-, or videotape) on which the information is recorded.

Measurements of the material configuration (e.g., 35 mm. (film), 12 inch (phonograph disc), 4" x 6" (microfiche)).

Physical substance applied to the material base (e.g., ink, oil, paint, specific photographic emulsions such as albumen).

Means or technique by which information was recorded in or on the material base (e.g., punched, pressed, cut, molded, thermofax, x-ray).

Physical material on or in which records are mounted, bound, or otherwise supported.

Normal rate or ratio at which the information in the material must be used to be meaningful (e.g., how many revolutions per minute for recordings, the magnification for photographic reductions).

Location of the described materials within the material base and configuration (e.g., band, page, frame number).

Access requirements involving technical equipment.

Part of the described materials to which the field applies.
