An auto-tracking apparatus of a magnetic recording/reproducing apparatus has a circuit for discriminating whether the audio signals recorded on a magnetic tape to be reproduced were recorded by audio rotary heads or a fixed head, and a circuit for selecting outputs of the audio rotary heads in the case of the Hi-Fi recorded magnetic tape by the audio rotary heads and outputs of the video rotary heads in the case where it is determined that the magnetic tape is the normal recorded tape by the fixed head on the basis of the result of the discrimination, and performs the auto-tracking on the basis of the selected outputs. With this arrangement, the auto-tracking can be carried out irrespective of whether the magnetic tape is the normal recorded tape by the conventional fixed head or the Hi-Fi recorded tape by the rotary heads.
