Abstract

An arrangement of magnetic heads comprising magnetic circuits for recording and reproducing magnetic signals, the effective air gaps of the magnetic circuits being viewed in the scanning direction of the recording carrier, arranged one after the other, characterized in that in the scanning direction the magnetic circuit that includes the reproduction gap is arranged before the magnetic circuit that includes the recording interlock and because both in recording and in reproduction the electric circuits of the circuits, magnetic to record and reproduce are electrically connected to each other, and during In the reproduction, the signal induced in the magnetic circuit for reproduction is preferably at least a factor of 10 greater than the signal induced in the magnetic recording circuit.
