Abstract

PURPOSE: To increase the limit frequency of high band reproduction, by using specific glass nature carbon greater in the Young modulus and less in density as the cantilever.
CONSTITUTION: Hardened phenol resin fiber in textile shape is immersed with phenol system resin such as novolak resin of 50% as the resin to be hardened, and it is molded to the shape of tapered cylinder or circular truncated cone, then it is heated to be hardened. The mold is gradulally risen in temperature under no-oxygen atmosphere, and after being carbonzied at temperature more than 800°C, it is gradually cooled. One end of the cantilever 3 made of glass nature carbon thus obtained is linked with the armature 1 supported elastically with the damper 2, and another end of the lever 3 is linked with the stylus chip 4, to constitute the pick up cartridge.
