<p>There is disclosed a slow-speed tape recorder drive mechanism. A slow-speed synchronous AC motor is spring-coupled to a pulley, which in turn drives a flywheel via a belt. A capstan pulley is driven via a second belt by the flywheel, and an intermediate pulley, driven via a third belt by the flywheel, is mounted for free rotation on the capstan pulley. This intermediate pulley drives a take-up pulley via a fourth belt. The surface speed of the capstan is less than one inch per second and at the operating speed the ratio of the inertia of the flywheel to the inertia of the capstan element is greater than 25:1.</p> |
