In this era where time is money, everybody is looking for high speed and high efficiency. For data transferring and backup functions the rotation speed is therefore of the essence. Optical disc drives nowadays use high rotation speeds that average over 10.000 rotations per minute, which in comparison is significantly faster than rotations speeds used in other consumer goods. For example, a walkman runs at an average of 400 rotations per minute.

At these extremely high rotation speeds, the safety and stability of the optical disc drives become very important. Designing a safe and stable optical disc drive is a test of skills for every manufacturer, including BTC.

High quality products do not only require powerful functions and good features, but perhaps even more important is their compliance with the laws of ergonomics. A good example is noise cancellation technology. BTC has done a successful job in finding ways to prevent noise by adopting a special structure design. This technology is called Sealed Acoustic Noise Isolation System (SANI). During high rotation speeds it has the effect of damping the noise by isolating the source of the noise. At the same time it makes the structure stronger, effectively blocks out dirt and lessens vibration.
