Abstract
A magnetic tape cassette transport/accessor assembly is actuated by a sprocket driven, belt drive system. First and second belt drives drive the transport/accessor assembly in horizontal and vertical directions and are tensioned by spring dampener assemblies. Each spring dampener assembly dampens rough and jerky movements and effects smooth and gentle acceleration and deceleration of the transport/accessor assembly. Each spring dampener assembly also provides compensation for belt drive wear, belt stretching and differential thermal expansion and contraction of the belt.
