Unlike US rulers, of which an overwhelming majority contain both centimeter and inch scales, tape measures are longer and thus traditionally have had scales in both inches and feet & inches. So, the inclusion of a metric scale requires the measuring device either to contain 3 scales of measurement or the elimination of one of the US Customary ...
The first commonly available increase in tape length resulted from a reduction in backing thickness from 1.5 to 1.0 mil (38 to 25 μm) resulting in a total thickness reduction from 42 to 35 μm (1.7 to 1.4 mils), which allowed 3,600 ft (1,100 m), 1,800 ft (550 m), and 900 ft (270 m) tapes to fit on ten-and-a-half-, seven-, and five-inch reels respectively.
Remanence of audio tapes, referred to quarter-inch tape width, varies from around 1100 G for basic ferric tapes to 3500 G for Type IV tapes; [5] advertised remanence of the 1986 JVC Type IV cassette reached 4800 G. [6] Coercivity is a measure of the external magnetic flux required to magnetize the tape, and an indicator of the necessary bias level.
These spools and their attendant parts are held inside a protective plastic shell which is 4 by 2.5 by 0.5 inches (10.2 cm × 6.35 cm × 1.27 cm) at its largest dimensions. The tape itself is commonly referred to as "eighth-inch" tape, supposedly 1 ⁄ 8 inch (0.125 in; 3.17 mm) wide, but actually slightly larger, at 0.15 inches (3.81 mm). [8]
Domestic consumer machines almost always used 1 ⁄ 4 inch (6.35 mm) or narrower tape and many offered slower speeds such as 1 + 7 ⁄ 8 inches per second (4.762 cm/s). All standard tape speeds are derived as a binary submultiple of 30 inches per second. Reel-to-reel preceded the development of the compact cassette with tape 0.15 inches (3.8 mm ...
The cartridge's dimensions are approximately 5.25 by 4 by 0.8 inches (13.3 cm × 10.2 cm × 2.0 cm). The magnetic tape is played at 3.75 inches per second (twice the speed of a cassette), is wound around a single spool, is about 0.25 inches (0.64 cm) wide and contains 8 parallel tracks.
