ABSTRACT:
In a rotating head type reproducing apparatus of the kind reproducing an information signal using rotating heads from a record bearing medium on which a plurality of pilot signals of different frequencies are recorded in rotation along with the information signal, one in every recording track in a predetermined sequence, the levels of pilot signals reproduced from mutually adjacent tracks by a first rotating head are compared with each other; and the result of comparison is used in detecting the tracking error of a second rotating head which is reproducing the information signal.
