摘要：
A write driver for an inductive load includes load terminals for connection to an inductive load, and an impedance-matched driver circuit responsive to first and second control signals to supply a drive current through the load in respective first and second directions. The inductive load includes an inductive write head and a transmission line of predetermined impedance connected to the write head for connection to the first and second load terminals. Ringing is suppressed by the impedance-matching of the driver circuit to the transmission line connecting the load to the terminals.
