The BBC solved the problem by using 52-centimetre (20 in) reels of magnetic tape that passed static heads at a speed of 5.08 metres per second (16.7 ft/s). VERA was capable of recording about 15 minutes (e.g. 4,572 meters) of 405-line black-and-white video per reel, and the picture tended to wobble because of some jitter (uneven speed) of the ...
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.
This allows use of the entire width of the tape, storing much more data per inch of tape, compared to the fixed head used in audio tape recording, which records a single track down the tape. The heads move across the tape at the high speed necessary to record the high-bandwidth video signal, but the tape moves at a slower speed through the machine.
The Signature V system came with a VR-1500 VTR, a black and white video camera, and a television set with tuner. It also contained an audio system with AM/FM tuner, stereo amplifier, an open-reel audio tape recorder, and stereo loudspeakers. The video camera included with the system was very large, weighing about 100 pounds.
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.
Overwriting a tape that was meant to be preserved was another potential mistake. [4] It was the tape librarian's responsibility to set up procedures for the handling of tapes to minimize the chances of errors taking place. [4] As one book of the era wrote, "keeping track of the whereabouts of the tapes is a formidable and responsible job." [1]
The 8-track tape (formally Stereo 8; commonly called eight-track cartridge, eight-track tape, and eight-track) is a magnetic-tape sound recording technology that was popular [2] from the mid-1960s until the early 1980s, when the compact cassette, which pre-dated the 8-track system, surpassed it in popularity for pre-recorded music.

Stand-alone tape management systems are predominant on mainframe platforms where tape is used as both a backup and base load storage medium.. Mainframe systems such as IBM's z/OS do provide some basic support for tape inventory control via the OS Catalog but as cataloging files is optional it is usually required that an additional software package does the following:
