Abstract
An apparatus for reproducing information from a track of a magnetic record carrier by means of a reproducing head divided into two reproducing portions. The apparatus comprises an amplifier circuit having a pair of input terminals, connected to the outputs of the two reproducing portions, a first signal combination unit, at least one variable gain amplifier and an output terminal. The controllable amplifier is connected between the output of the signal combination unit and the output terminal of the amplifier circuit. The gain of the amplifier is controlled in such a way that upon application of the two signals to the input terminals of the amplifier circuit, a signal is obtained on the output terminal having an amplitude u which is in a fixed ratio to the amplitude of the larger of the two signals applied to the two input terminals.
