Abstract
In a reproducing apparatus for reproducing an information signal from a recording medium on which a number of recording tracks are formed in parallel to each other and on which the information signal is recorded with a pilot signal component superimposed on the information signal periodically at intervals of a predetermined number of tracks, a pair of reproducing heads are arranged to reproduce signals by concurrently tracing mutually adjacent tracks, a switching part is arranged to selectively output the signals reproduced by the reproducing heads, and the pilot signal component included in the output of the switching part is used in controlling the positions of the reproducing heads relative to the recording medium.
