Commentary
MM cartridge using beryllium pipe cantilever.
Model equipped with carbon fiber shell on PC-1000/II.
The cantilever consists of a 30 μ m beryllium pipe with an outer diameter of 0.5 mm, which is precisely molded into a pipe shape. As a result, 0.26 mg of beryllium is lighter in weight. In addition, the stylus tip, which is made by grinding the tip of natural diamond into an elliptical shape of 0. 2x0. 7 mil, enhances the tracing capability of large amplitude and ultra-high frequency waveform.
By adopting a single-end support system to clarify the vibration supporting point, the mechanical impedance in the high frequency range is reduced.
By using 21 suspension wires braided in a non-rebounding spiral shape, cross modulation distortion is greatly reduced.
The magnetic circuit uses 3-layer laminated pole pieces, ferrite yokes with high magnetic efficiency, and rare-earth cobalt magnets with light mass and high energy to realize wide-band reproduction.
