Abstract
A current driver circuit for writing data to a hard disk receives an input signal and generates a current for driving a load. A drive circuit supplies the load with a current. A damping circuit connected to the drive circuit restricts the current supplied to the load in accordance with a pulse signal. A damping control signal connected to the damping circuit generates the pulse signal in response to the input signal and provides the pulse signal to the damping circuit.
