A device for recording an information signal on a magnetic record carrier (2) includes a write amplifier (3), a magnetic head (4) of the magnetoresistive type, and a compensation circuit for controlling the amplitude of the write current in dependence upon temperature variations which occur during recording. The compensation circuit includes an actuator for bringing the record carrier into contact with the magnetic head (4) before a recording is started. In addition, detector means (17, 18) is provided to detect an output signal of the magnetic head produced as a result of the magnetic head being brought into contact with the record carrier. A control signal generator (17) generates a control signal whose magnitude is a measure of the magnitude of the output signal. The compensation circuit (3, 5, 8, 11, 17) is adapted to control the amplitude of the write current in dependence upon the control signal.
