Commentary
MM type cartridge using high energy platinum-cobalt magnet.
High-energy platinum and cobalt magnets are used for the vibrator, and the best magnet in the world at that time (maximum energy product 14x106G ・ Oe) to reduce the weight of the vibrator.
The needle tip uses a 0.15 mm square oval block diamond, and the tip has undergone a smooth complete polishing process.
In addition, it uses a 0. 2x0. 7 mil long elliptical needle to obtain excellent characteristics.
The vibrator support structure by one point support suspension wire system is adopted to improve the transient characteristics.
It uses a 0.35 mm ultra-lightweight titanium pipe cantilever and realizes an effective mass of 0.4 mg of the vibrator.
