a write driver circuit selectively provides write current through a write head in first and second opposite directions . first and second active devices are driven with first and second pre - drive signals . third and fourth active devices are driven with third and fourth pre - drive signals . first and second pull - up resistances are provided respectively between the first and second active devices and a fixed voltage , and third and fourth pull - up resistances are provided respectively between the third and fourth active devices and the fixed voltage . a first capacitor is connected between the first active device and an intermediate point of the third pull - up resistance , and a second capacitor is connected between the second active device and an intermediate point of the fourth pull - up resistance .
