Dual pinch rollers are also used (along with dual capstans) in auto reverse cassette decks to drive the tape in both directions as needed.
Variations in tape speed cause flutter, which can be reduced by using dual capstans.
Another type of demagnetizer, the wand type can demagnetize anything that it is brought into contact with, including the tape heads and capstans.
The sclerites are red, some being irregular and shaped like miniature capstans.
Each gate leaf had two capstans, one to open it and another to close it.
Multiple capstans of differing diameters vary the tape speed over a single stationary magnetic tape head.
Later capstans were made entirely of iron, with gearing in the head providing a mechanical advantage when the bars were pushed counterclockwise.
The heads and other metallic components in the tape path (such as spindles and capstans) may become magnetized with use, and require degaussing.
