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.
Travan is an 8 mm magnetic tape cartridge design developed by the 3M company, used for the storage of data in computer backups and mass storage. [1] Over time, subsequent versions of Travan cartridges and drives have been developed that provide greater data capacity, while retaining the standard 8 mm width and 750' length.
The IEC reference tape bias definition is: Using the relevant IEC reference tape and heads according to Ref. 1.1, the bias current providing the minimum third harmonic distortion ratio for a 1 kHz signal recorded at the reference level is the reference bias setting.
At the end of the tape, the drive reversed the direction of tape motion, moved the read and write heads slightly vertically across the tape, and continued to write (or read) more data until the beginning of the tape was reached. This process could be repeated many times, laying down several track sets on the tape media in a serpentine recording ...
[8] [9] The name was soon applied to the entire line of 3M tapes. Scotty McTape, a kilt-wearing cartoon boy, was the brand's mascot for two decades, first appearing in 1944. [10] The familiar tartan design, a take on the well-known Wallace tartan, was introduced in 1945. [10] The Scotch brand, Scotch Tape and Magic Tape are registered ...
Early half-inch tape had seven parallel tracks of data along the length of the tape, allowing 6-bit characters plus 1 bit of parity written across the tape. This was known as 7-track tape . With the introduction of the IBM System/360 mainframe, 9-track tapes were introduced to support the new 8-bit characters that it used.
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 late 1980s, when the compact cassette, which pre-dated the 8-track system, surpassed it in popularity for pre-recorded music.

This is used with audio tapes to control playback. A typical scenario has an audio recording on the "left" track and short bursts of 5327 Hz at key locations within the audio. The program then starts the tape motor, causing the audio to be routed through the television speaker, waiting for a 1 to appear on the I/O port.
