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.
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.
IBM Magnetic Tape/Selectric Composer (MT/SC) in use Panel of MT/ST. The IBM MT/ST (Magnetic Tape/Selectric Typewriter, and known in Europe as MT72 [1]) was a model of the IBM Selectric typewriter, built into its own desk, integrated with magnetic tape recording and playback facilities, located in an attached enclosure, with controls and a bank of relays.

Pressure-sensitive tape or pressure-sensitive adhesive tape (PSA tape) is an adhesive tape that sticks when pressure is applied without the need for a solvent (such as water) or heat for activation. It is also known in various countries as self-stick tape , sticky tape , or just adhesive tape and tape , as well as genericized trademarks , such ...
A gap (initially one inch, later 3/4 inch) between records allowed the mechanism time to start and stop the tape. Latency There was only a 1.5 ms delay for the stopped tape to reach its full reading or writing speed. Markers Aluminum strips were glued several feet from the ends of the tape to serve as logical beginning and end of tape markers.

Threaded tape of an open Compact Cassette in the tape drive. The capstan is a rotating spindle used to move recording tape through the mechanism of a tape recorder.The tape is threaded between the capstan and one or more rubber-covered wheels, called pinch rollers, which press against the capstan, thus providing friction necessary for the capstan to pull the tape.
9-track tape drive used with DEC minicomputers Inside a 9-track tape drive. The vacuum columns are the two gray rectangles on the left. A typical 9-track unit consists of a tape transport—essentially all the mechanics that moves tape from reel to reel past the read/write and erase heads—and supporting control and data read/write electronics.
