19 ABSTRACT: In accordance with a method of recording and/or reproducing stereophonic information in two adjacent tracks of a magnetic record carrier an auxiliary signal whose frequency content is situated beyond the frequency spectrum of the stereophonic information is recorded in the tracks and in the magnetic record-carrier area between the tracks during recording. During reproduction use can be made of the auxiliary signals read from the record carrier by the two transducers in order to obtain a control system which ensures that the amplitude of the stereophonic information thus reproduced becomes independent of tracking errors.
