It all began when Micha Huber sought for a way to combine the advantages of a conventional pivoted tonearm and those of a linear tangential pick-up arm. The solution method is based on the well-known elementary school aid to construct a tangent: the Thales' circle. After much thought and calculations, a three-dimensional mechanical solution emerged that satisfies all the requirements placed on a modern pick-up system.
The long-cherished dream of geometrically correct tracking with low friction pivoted bearings became reality. A new patent was added to the dozens of existing patents that testify to this dream: CH 694567 Tangential Pivoted Tonearm, announced in May 2004.
