> The smoothing out is done by the elasticity of the belt which provides mechanical isolation and by a flywheel. With the exception of one esoteric Eumig brand deck, all cassette decks have flywheels. I just had to look this up. Interestingly the Eumig tape deck used a small mechanical fan to dampen the tape movement. The white fan can be seen in the third and fourth pictures on this site: http://www.captndifool.de/index.php/cassettendecks/eumig/eumig-fl-900 http://www.captndifool.de/index.php/cassettendecks/eumig/eum...
