Abstract
A circuit is provided to switch a drive transistor in a write driver circuit controlled by a write control signal to direct write current in a selected direction through an inductive head. Current is selectively conducted from a control region of the drive transistor in response to switching of the write control signal. A first bias circuit limits voltage fluctuation at the control region of the drive transistor. A second bias circuit prevents saturation of the drive transistor.
