This is a unique pivoted tonearm that
- Tracks across the tangent of the recorded grooves, similar to a Linear Tracking tonearm.
- Has no headshell offset, so therefore does not require anti-skating.
(Unique today, but I vaguely recall historically at least one other pivoted tonearm design that was cleverly designed to track the groove tangent?)
Conventional pivoted tonearms, as we know, track an arc that achieves zero tracking error at only 2 groove-tangent points across that arc.
The Schröder LT's base itself is not stationary, it rotates in a small arc whilst the cartridge is tracking another bigger arc - maintaining 'tangency' to the grooves (somehow
)....
There is also some magnet 'damping' involved.
Some drawings from Frank Schröder's 2012 patent application....
