Scotchcart / Scotchcart II (mid 1980s – late 1990s)


Scotchcarts were a development of Fidelipac, and like Fidelipac and other broadcast cartridges, was used in radio broadcasting for playback of material such as radio commercials or jingles.

Introduced in the mid-1980s by 3M, Scotchcarts have no tape hub, and the tape pack sits on a white plastic support. This means there is no reel mass, so the tape stops and starts faster, there is smoother tape movement and fewer moving parts.

There was an adjustable ‘Life Extension Cam’ which adjusts the diameter of the split tape support inner ring, thereby adjusting tape pack tension. Combined with the tension arm, this provided an extremely well-regulated tape tension system, eliminating the need for pads.

The only difference between a Scotchcart and a Scotchcart II is the tape and the colour of the cartridge (Scotchcarts are brown, while Scotchcart IIs are black).

Like other broadcast cartridge formats, formats as MiniDisc and computerised broadcast automation made it obsolete by the late 1990s.
