摘要：
A magnetic storage circuit comprises a preamplifier writer that selectively generates a write current that has a boost stage and a settling stage. An impedance changing circuit communicates with the preamplifier writer and provides a lower resistance value during the boost stage and a higher resistance value during the settling stage.
