APPARATUS FOR REPRODUCING INFORMATION FROM A TRACK OF A MAGNETIC RECORD CARRIER

摘要

27 An apparatus for reproducing information from a track of a magnetic record carrier by means of a reproducing head divided into two reproducing portions comprises an amplifier circuit having a first and a second input terminal, which terminals are connected to the outputs of the two reproducing portions, a first signal combination unit, at least one controllable amplifier, and an output terminal. The controllable amplifier(s) is (are) arranged in the connection from the input terminals of the amplifier circuit to the first or second input of the signal combination unit. Control is effected in such a way that upon application of two signals (X1 and X2) of at least substantially equal phase to the first or second input terminal respectively a signal is obtained on the output terminal which has an amplifier u which is in a fixed ratio to the amplitude of the larger of the two signals applied to the two input terminals.
