An H-bridge driver for a disk drive system includes first and second high side switched legs and first and second low side switched legs. An inductor head for writing data to and reading data from a magnetic media is connected to form a center of the H-bridge. The system includes a voltage regulator circuit that generates a common mode regulated voltage. First and second high side logic circuits, which selectively control operation of the first and second high side switched legs, are coupled between a high reference voltage and the common mode regulated voltage. First and second low side logic circuits, which control the first and second low side switched legs, are coupled between the common mode regulated voltage and ground.
