发明名称 Reproducing apparatus
摘要 An apparatus for reproducing information signals from a record bearing medium having the information signals recorded together with different pilot signals which are repeatedly recorded, one after another, in a plurality of recording tracks. The apparatus includes a reproducing device arranged to trace the recording tracks on the record bearing medium; a reference signal generating device for generating reference signals which have frequencies corresponding to the pilot signals; a detection signal generating device for generating a plurality of detection signals having different frequency components by using the pilot signals reproduced by the reproducing device and the reference signals; and a tracking error signal generating device for generating a tracking error signal by utilizing the different frequency components of the detection signals.
