High reliability thanks to our 40 years of knowledge and production Because of their quiet, smooth operation, rubber belts are widely used to operate the disc tray loading/unloading mechanism in DVD and BD (Blu-ray Disc) optical disc drives and to transmit drive power in audio equipment. Yamauchi supplies rubber belts for VCRs and audio products to almost all audio/visual equipment manufacturers in Japan. Drawing on this experience, we produce 10 to 15 million high-quality drive belts per month and supply them to PC and AV equipment manufacturers around the world.
