REGISTRY OR REPRODUCTOR DEVICE FOR REPRODUCING OR REGISTERING IN AN OPTICAL REGISTRY MEANS.

摘要

The invention is related to a reproduction or registry device for reproducing or for registering in an optical registry means having a follow-up synchronization circuit (1) which has a variable central frequency generator (12, 13). The follow-up synchronization circuit (1) can be operated with different central frequencies that depend on the application and that have the advantage of follow-up synchronization circuits (1) identically designed which can be used for different purposes. It is advantageous that the adaptive adjusting of a central frequency once prescribed is additionally possible during the operation, in this way increasing the capture range of the follow-up synchronization circuit.
