    Abstract: A capstanless, reel-driven tape drive with little tape speed or recorded density variation. A differential mechanism has its carrier connected to a drive motor and its outputs connected respectively to the two reel spindles to obtain a solely reeldriven tape. A feedback for velocity control is obtained via the tensioned tape.
