Magnetic recording device
A magnetic recording device capable of reducing the size of a writing circuit and the power consumption by readily adjusting the overshoot of the write current pulses is provided. Two or more transmission lines having different characteristic impedances are provided between an output driver having an impedance Zs and a magnetic head, the transmission lines are formed so that the characteristic impedances Z1, Zn−1, and Zn (n≧2) thereof on the output driver side are higher than those on the magnetic recording head side (Z1>Zn−1>Zn), and the impedance Zs of the output driver is equal to or higher than the characteristic impedance Z1 of the transmission line.
