Deformation Distortion in Disc Records

The distortion produced by groove-wall deformation in accordance with the elastic theory of Hertz, combined with the distortion produced by tracing error, is calculated using an extension of the power-series approach of Lewis and Hunt in their treatment of tracing error. The dynamical differential equations for the several components of deformation error representing resonant systems are derived and solved for the distortion components. Numerical results for certain parameters are presented graphically, and the relative importance of various terms is appraised. It is seen that the second harmonic term, for example, arising from tracing error, is reduced by the action of deformation error, away from resonance. For an isotropic sylus impedance there is no cross-coupling between stereo channels in the absence of friction, but a beginning at an analysis of friction suggests a mode of coupling.
