Commentary

This VF (variable flux) type stereo cartridge was developed based on the results of R & D and experience with the M-1007 series and M-2000 series announced by Micro-Seiki Co., Ltd. as the final version of MM type cartridge.

We have succeeded in changing the cross-sectional area and shape of the cantilever in one piece for the first time in Japan by developing our own precision machining technology.
The rear part of the cantilever is made into a rectangular column shape, and the vibrator is contained in it. The part which changes from the rectangular column shape to the cylindrical part is made into a conical shape, and a special curing process is applied on it.
As a result, the cantilever can be regarded as one rigid body, and the pick-up force for sharp transients and large amplitude in low frequencies, which was difficult with conventional methods, has been improved.

A twin damper system has been adopted for the damper part, and two types of damper materials with different hardness, viscosity, and elasticity have been successfully integrated at the molding stage without sticking together.
Since this twin damper is a composite of two types of damper materials with different characteristics, special characteristics that cannot be obtained with conventional dampers can be obtained.

Since the rear end of the conical cantilever is supported by a special twin damper, compliance is large, and changes in the vibrator can be extracted as changes in magnetic flux.
In addition, along with the high compliance, the tracking ability to the sound groove of the needle tip is improved, and the resonance point in the high-frequency range can be raised.

Natural diamond elliptical needle of 0.8 mil long diameter and 0.3 mil short diameter is used for the needle tip.
The elliptical needle reduces the pinch effect distortion and tracing distortion compared to the round needle, realizes the characteristics of frequencies above 25 kHz, and improves the channel separation in the high frequency range.

Since the needle replacement is a plug-in method with a mold tip, it can be replaced with the same feeling as MM type.

Since the screw holes conform to JIS and EIA standards, the tone arm based on this standard can be mounted as it is.
