WELL TEMPERED - REFERENZ LAUFWERK - ROYALE 400

The objective was to analyze tracking angle problems from a graphical perspective rather than from a mathematical perspective dealing with pages of equations. Now the Tracking Angle Analyzer has been used to see if a longer arm could eliminate or minimize skating forces on the cartridge stylus. This approach has proved successful and has led to the conception of The Well Tempered Royale 400 with an arm length of 16 inches or about 400mm. Using the Tracking Angle Analyzer to determine the geometric parameters reveals the following: with an overhang of 0.25 inches and a tracking angle of 11 degrees, there will be 1.5 degrees maximum tracking angle error at the outer most grooves and approximately 1 degree of tracking angle error over the rest of the record surface.

This geometry, with a small overhang, satisfies the objective of the Royale 400. Overhang of course causes skating forces and with an over hang of only 0.25 inches, there is barely any skating force and the residual skating force is eliminated by the twist of the filament suspension system.

Measurements of the residual skating force indicate that it is less than 0.1 gram and is thus inconsequential.
