ABSTRACT:
An apparatus for reproducing recorded signals by periodically tracing with reproducing heads many recording tracks formed on a record bearing medium, is arranged to form from the output of the reproducing head a first periodic signal relative to a tracking error between the head and one of many recording tracks; and to control the movement of the record bearing medium relative to the reproducing head on the basis of a phase difference between the first periodic signal and a second periodic signal which is related to the tracing period of the reproducing head.
