AB  - A number of observations are reported on an improved disc reproducer consisting of a tone arm and cartridge assembled as a matched system. Interchangeable stylus assembleis with spherical or biradial tips were used with conventional test records. Since only the stylus assemblies were changed, the effects caused by changes in tip radii are readily seen. The data touch on several problems involving biradial and spherical stylus relationships for which a theoretical model is incomplete, especially such effects of biradial styli as extremely high stress imposed on the record groove and the possibility of shorter record life. Record wear data are shown for the biradial stylus which indicate that record life is about the same as with a spherical tip, when both are used in low-inertia assemblies.
