Abstract

Carbon fibre cantilever. Heat sensitive resin of 30-40% weight value of carbon fibres is impregnated into carbon fibres under heat and pressure. Vertical elastic ratio E of carbon fibre cantilever is 14000kg/mm2 (7000kg/mm2 for aluminium), and its density is 1.2 (2.7 for aluminium). Fig.1: Conventional stylus with aluminium pipe cantilever. Fig.2: Section of cartridge having invented cantilever. Fig.3: Section of invented cantilever. Fig.4: Frequency responses for conventional and new cantilever with 1 conventional aluminium cantilever, 2 tip, 3 magnet, 11 new cantilever, 11 carbon fibres, 12 stylus, 13 magnet, 17 sag with conventional cantilever, 18 improved response by using new cantilever, 19 separation with conventional cantilever, 20 separation available with new cantilever.
