PURPOSE:To improve serviceability by setting the constant of each magnetic head at the optimum value, by connecting a damping resistor corresponding to the magnetic head. CONSTITUTION:The damping resistors 17 and 18 consisting of outfitting components are connected to an IC 10 which constitutes a recording and reproduction circuit. Those resistors 17 and 18 constitute the damping resistors for read and write, respectively. Furthermore, it is constituted so that the damping resistors 21 and 22 can be connected to the magnetic heads 21 and 22. Those resistors 21 and 22 are mounted on a head carriage 15 side. In other words, by switching change-over switches 24, 25, and 26, the damping resistor 21 on the head carriage 15 side is connected in parallel with the damping resistor 17 for read, or in parallel with the damping resistor 18 for write. In such a way, it is possible to use the magnetic head being arranged oppositely to a recording medium with the optimum constant, and to improve the serviceability. |
