  • Abstract
    This paper describes a high-speed circuit for driving magnetic recording write heads. Resonant current switching enables a reduction in power consumption without compromising switching speed. With a 100 nH load and 120 mApp write currents, a rise time of 1.6 ns was achieved with a 7 V power supply
