Commentary
High-grade MM type cartridge with lightweight vibration system.
A 0.41 mg vibration system has been realized by adopting a lightweight titanium pipe cantilever.
The tip of the 0.15 mm square ultra-small block diamond has been polished to an elliptical shape of 0. 3x0. 7 mil to reduce tracing distortion and obtain flat characteristics over audible frequencies.
Since the vertical tracking angle is adjusted to the record cutting angle of 15 °, the distortion of the matrix 4 ch record is also reduced.
Excellent compliance is obtained by the adoption of special shape damper.
