In today's digitized society, optical disc drives play a very important role. Like socks in shoes, optical disc drives in PCs are simply indispensable! As a medium to transfer or store important data files such as digital property, optical disc drives already have an irreplaceable key position.

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.
