A recording head drive circuit drives a recording head that records information on a magnetic recording medium. A switching circuit is a H-bridge circuit which includes a plurality of transistors. The switching circuit switches direction of a write current (Iw) flowing in the recording head, in accordance with a conduction state of each transistor. A write current controller controls the write current (Iw) in the recording head. An overshoot control circuit adds an overshoot current (Ios), proportional to the write current (Iw), to the write current (Iw) flowing in the recording head, in a predetermined overshoot time period.
