It is man-month type cartridge which attained highly efficient-ization by adopting new technology and new materials.

The pivot support which carries out the Tip-of-the-Day support of the supporting point of vibration system is adopted.
And since it fixes with the jewel which had the oscillating supporting point selected carefully, even if compliance is high, there is no disorder of a mechanical impedance.

The magnetic circuit of C form yoke which uses the newly developed samarium cobalt magnet is developed and carried.

The damper rubber of form and the quality of the material suitable for a pivot support scheme was severely examined and chosen as damper rubber, and is adopted as it.

In a shielding case, the specification of the permalloy material of highest-class 3 yuan is carried out to very deep throttle form, the influence of an external magnetic field is intercepted, and the hum by the turntable and a motor is pressed down to it.
