Prior to the development of the tape dispenser, 3M's standard clear scotch tape was sold as a roll, and had to be carefully peeled from the end and cut with scissors. To make the product more useful, the scotch tape sales manager at 3M, John Borden, designed the first tape dispenser in 1932, which had a built-in cutting mechanism and would hold the cut end of the tape until its next use.

Quarter inch cartridge tape (abbreviated QIC, commonly pronounced "quick") is a magnetic tape data storage format introduced by 3M in 1972, [1] with derivatives still in use as of 2016. QIC comes in a rugged enclosed package of aluminum and plastic that holds two tape reels driven by a single belt in direct contact with the tape.
Binary tapes used odd parity (709 manual, p. 20). Aluminum strips were glued several feet from the ends of the tape to serve as physical beginning and end of tape markers. Write protection was provided by a removable plastic ring in the back of the tape reel. A 3/4 inch gap between records allowed the mechanism enough time to stop the tape.
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.
