AB  - The cartridge described in this paper is a high performance moving magnet cartridge of original one-point suspension type, employing a disc-shaped high energy Sm-Co magnet in its electrical generating system. The major featureof this cartridge is the pure boron tapered pipe cantilever which contributes to a low effective moving mass (only 0.098mg). Another original development is the damper material used which effectively resists temperature changes in response characteristics. This is achieved by its specific viscous elastic characteristics. For magnetic transfer, this cartridge employs mirror polished HPF (Hot Pressed Ferriete) exhibiting excellent high range frequency response characteristics. As a result, this cartridge is capable of a frequency response extending from 5Hz to 100kHz, it also exhibits very low mechanical impedance and improved tracing ability.
