Using a stainless steel material with a high specific density, the record board is brought into close contact with the turntable and mechanical resonance is suppressed. The groove trace becomes accurate, and the clearness and resolution of the reproduced sound are improved. In order to repeatedly “put and remove” on the record board, we examined the design so that it would not fall, and as a result, we made a unique shape that deeply scooped out the record board side. It is a universal design that hooks and lifts all fingertips without relying on muscle strength. The main body is cut with high precision by NC processing machine, and all domestically produced parts including the package are used. The top surface is processed into rough spins to achieve both brilliance and prevention of fingerprint adhesion.
