Conventional transducer with aluminium cantilever
The diamond tip is fixed to a cantilever made of aluminium. Since aluminium is a relatively soft material, the high-dynamic tracking process causes deformation of the cantilever and therefore distortion of the signal. Moreover, there is a joint between cantilever and coil body, which, due to lever action, carries the highest dynamical load of the transducer and cannot pass on the movement without loss.
