Abstract
In a magnetic recording writing circuit, a current having a higher level than a write current is supplied for a period of time during rise and fall of the write current, and a current having a lower level than the write current is supplied for a period of time during overshoot at the rise and fall of the write current. Accordingly, the write current can recover quickly from overshoot.
