Abstract
The kinematic principles involved in tracking-error elimination in automatic turntables are described. Following a discussion of conventionally pivoted designs, a procedure is developed for the kinematic synthesis of an articulated tone-arm system (Garrard Zero 100), in which essentially true-tangent tracking is achieved throughout the playing of the record. The synthesis problem is formulated as the approximation of cardanic motion or slider-crank connecting-rod motion by means of four-bar motion over a finite range of displacements. The results, which are compared to the Garrard design, show that tracking error can be reduced to approximately 20 sec of arc.
