Abstract
An improved capstan for a tape drive of the type for attachment to the shaft of a drive motor, the capstan being formed of a body having low mass and providing a cylindrical tape engaging surface and means for axially securing the body to a motor shaft. The capstan body has a radial sidewall. A thin disc of a diameter no greater than that of the capstan is secured to the radial sidewall by a layer of compliant adhesive. The layer of adhesive serves to provide resilient energy-absorptive rotation movement between the capstan body and the disc to reduce the effect of capstan resonance.
