Several years ago, Cyrus invested heavily in developing our own in-house CD ‘Servo’ mechanism, our ‘Servo Evolution’. The design principle is to read as much information as possible from the disc itself first time, rather than having to rely on ‘re-reads’ or ‘error-correction’.

Whilst it is true that the data on a CDs is stored in ‘1s and 0s’, the way it is read, using picking up different frequencies of reflected light, has analogue elements to it.  Therefore, precision engineering can improve the performance.  Off-the-shelf mechanisms produce significant ‘system noise’ when the stepper motors of the mechanism are required to be used during the error correction processes when the data was not picked up on the first pass.  Our ‘Servo-Evolution’ system reduces these re-reads and corrections by around 20%, producing not only a cleaner data stream, but significantly less noise.
