ABSTRACT:
An apparatus for reproducing signals from a multiplicity of parallel tracks in a recording medium by means of n number of rotary heads, n being an integer not less than 3. A transportation device for transporting the recording medium is controlled on the basis of two kinds of signal: namely, a tracking control signal for leading one of the n number of rotary heads to one of m number of tracks contained in consecutive n number of tracks, m being an integer not less than 2; and a track shift signal which is generated in accordance with the result of a determination as to whether the n number of rotary heads are tracing expected tracks and which enable the tracks under tracing to be shifted to obtain a predetermined relationship between the sequence of the n number of rotary heads and the sequence of the tracks traced by these rotary heads.
