A magnetic storage device equipped with a write driver circuit is provided. This magnetic storage device includes: four current sources each provided at a corresponding one of the four sides of an "H-bridge" circuit; a magnetic head provided at the bridging part of the "H-bridge" circuit; and a series circuit including capacitors and terminating resistors. A separate series circuit is provided between the ground and each corresponding one of the connection points of the bridging part and the four sides of the "H-bridge" circuit. With this magnetic storage device, impedance matching can be easily performed. Also, a smaller circuit size can be realized, and accordingly, the power consumption can be reduced. Furthermore, desired recording can be performed at a high transfer rate.
