Abstract
A pickup cartridge comprising a cantilever and a stylus attached to the free end of the cantilever. The cantilever is formed with a flat portion and a ribbed portion extending along the length of the flat portion so that the transverse cross-section of the cantilever is of a cruciform configuration. The flat and ribbed portions are dimensioned so that the cantilever tends to oscillate at a frequency different from the resonant frequencies of disc records.
