On the Interaction between Tracing Correction and a Bandwidth Limitation
A double-bandwidth requirement proposed by Hunt as necessary to the making and reproducing of tracing-corrected recordings is shown to be irrelevant to the reproducing element by an argument using a factoring demonstrated by Miller. The implications of Miller factoring in explaining the residual distortion in tracing-corrected recording as being essentially the sole result of an ameliorated deformation error are sketched. Analysis of numerical examples of interactions between tracing correction and bandwidth limitations for the recording element shows the interaction to be of negligible consequence for practical cases. An argument is made that the full realization of the growth potential of disc-recording technology requires tracing error to be eliminated though a correct shaping of the groovewall waveform to favor the use of low-deformation styli in playback.
