Servomechanism for recording disk reproducing system

摘要

A servomechanism for a recording disk reproducing system which includes a switching device receptive of the analog error signals of a variety of servo systems for outputting the same analog error signals sequentially in a time division manner in response to sampling signals of predetermined frequency. The analog error signals passed through the switching means are converted into digital error signals and subjected to arithmetic processing. The processed digital error signals are reconverted into analog error signals and distributed to the respective controlled portions of the various servo systems in synchronism with the sampling signals. The frequency of the sampling signals is set on the basis of that of a reference signal contained in the signal read from the disk being played.
